  • IE8 is still caching my requests even with mathrandom.

    - by Ozaki
    TLDR IE is still caching my requests even with Math.random() included in the URL. So I added math random onto the end of my url: var MYKMLURL = 'http://' + host + 'data/pattern?key='+ Math.random(); I also added math random onto my function param: window.setTimeout(RefreshPatternData, 1000, MYKMLLAYER); function RefreshPatternData(layer) { layer.loaded = false; layer.setVisibility(true); layer.refresh({ force: true, params: { 'key': Math.random()} }); setTimeout(RefreshPatternData, 30000, MYKMLLAYER); } So the request appears as http://host/data/pattern?key=35678652545 etc. It changes everytime the request is made. It works in Firefox & Chrome & Safari etc. But IE8 is still caching the data and not updating my layer. Any ideas as to why this might be occuring?

  • Display Image over map layer in GeoServer

    - by iririr
    Hi I am newbie when it comes to GeoServer and trying to figure out if there is an easy way to display images on top of map layer. A background: In my application, based on a search criteria, some polygons are drawn on the map. Each polygon has a corresponding image (in TIFF format) that is stored somewhere. I want to load the image on top of the map when the user zooms in to a certain zoom level. I know this can be done using openLayers but since my images are in TIFF format, (openLayers is not able to render TIFF images as far as i know) i have to convert them to .PNG first which would be very slow considering the number of images i have. Hence I was wondering whether it would be possible to create a image layer that would retrieve an image of a certain polygon at a certain zoom level. If so, could anyone point me to an example or give me an idea on whether this is possible. I am using spring 2.5, tomcat 5, java 1.6 and geoserver 2.0 Thanks.

  • error 20014 with mod_proxy

    - by punkish
    I have strange situation. I need to call a program in cgi-bin from within a perl script. When I try to do that with exec($program), I get (20014)Internal error: proxy: error reading status line from remote server proxy: Error reading from remote server returned by ... The long story... I am calling mapserv (http://mapserver.org) as a cgi program from OpenLayers (http://openlayers.org). Ordinarily, my web site is served by Perl Dancer, but the mapserver calls are made directly to http://server/cgi-bin/mapserv from JavaScript. The Dancer web site is served by Starman behind an Apache2 proxy front-end. This is how it looks [browser] -> http://server/app -> [apache2] -> proxy port 5000 -> Starman | | +-> http://server/cgi-bin/mapserv -> [apache2] -> cgi-bin -> mapserv This is what I am trying to accomplish [browser] -> http://server/app -> [apache2] -> proxy port 5000 -> Starman | | mapserv <-- cgi-bin <-- [apache2] <--+ I saw this question re: 20014 error, but that suggested solution didn't help. Any other hints?

  • Custom map solution using openstreetmap

    - by LearneR
    I want to work in real estate portal and I need to filter the result and list the properties in map view using openstreetmap (Client requirement). They gave this reference site . I started on yesterday only but the documentation and all I am not able to understand (as a beginner). Can we implement like this using openstreetmap? Where should I start at first? Also I have seen some of the users recommended openlayers, leaflet, mapquest in help answers. Which one is best for my requirement openstreetmap or thirdparty api? Please guide me to complete this task. I don't know where I am and where I have to start?

  • ExtJS data store for tree

    - by drewda
    I've got a basic ExtJS question, which I can't seem to resolve based on reading the docs and searching. Currently I have a TreePanel that loads JSON directly from a URL. I'm trying to separate the data from the view, so that I can also use that data to feed into an OpenLayers map (using GeoExt). How can I point a TreePanel to an Ext.data.Store rather than to a URL?

  • ExtJS - Save State of treePanel.

    - by Ozaki
    TLDR I want my treepanel from EXTJS to remember its previous settings. ExtJS-3.2.1 I have seen this done before for ExtJS-2.x.x :See here on the extjs forums. But as seen as they are pretty much lifeless, with threads on there asking this question or similar with no reply for up to 6months. I thought I would bring it here. I need to be able to get my treePanel to remember previous opened folders and which boxes are checked. It is async treePanel. Panel is as follows: var layerTree = new Ext.tree.TreePanel({ border: true, region: "east", title: 'LayersTree', width: 250, split: true, collapsible: true, collapsed: true, iconCls: 'treePanelIcon', enableDD: true, autoScroll: true, //pulls in layers and their attributes// root: new Ext.tree.AsyncTreeNode({ leaf: false, loaded: false, expanded: true, text: 'Tree Root', children: treeLayers }) Am using ExtJS-3.2.1, GeoExt, OpenLayers. Anyone done this before or know how to do it? (Preferably with a plugin but any answer is appreciated)

  • Delay function from running for n seconds then run it once. (2minute question)

    - by Ozaki
    TLDR I have a function that runs on the end of a pan in an openlayers map. Don't want it to fire continously. I have a function that runs on the end of panning a map. I want it so that it will not fire the function until say 3 secconds after the pan has finished. Although I don't want to queue up the function to fire 10 or so times like setTimeout is currently doing. How can I delay a function from running for n seconds then run it only once no matter how many times it has been called?

  • IIS 7 URL Rewrite to GeoServer running on Apache

    - by Maxim Zaslavsky
    I'm building a mapping application based on OpenLayers that uses GeoServer to serve up mapping data. The problem I'm having is that besides the map images I'm requesting through WMS, I'm using jQuery AJAX to get information from GeoServer. As GeoServer is running on a different port, my requests are being blocked due to cross-site scripting security policies in JavaScript. As a Java application, GeoServer runs on Apache on port 8080, while my IIS instance is running on port 80. Instead of building a proxy, I've decided to use URL Rewriting in IIS7 to fix this problem. I'm following this guide, but it's still not working. Here are my URL Rewrite rule settings: Matches URL: (.*) Condition: {HTTP_URL} matching /geoserver Action: rewrite to http://localhost:8080/{R:1}, appending query string When I request http://localhost/geoserver/wms?QUERY_LAYERS=SanDiego:FWSA_sandiego&LAYERS=SanDiego:FWSA_sandiego&SERVICE=WMS&VERSION=1.1.1&FEATURE_COUNT=20&REQUEST=GetFeatureInfo&EXCEPTIONS=application/vnd.ogc.se_xml&BBOX=-13009123.590156,3862057.2905992,-13006066.109025,3865114.7717302&INFO_FORMAT=text/html&x=20&y=20&width=40&height=40&srs=EPSG:900913, however, all I get is a 404, although the same request on port 8080 returns the proper result. What am I doing wrong? Thanks in advance.

  • Open source GIS tools

    - by TRV_SQL
    Hi I’ve been looking at Open Source GIS tools. In particular MapServer and GeoServer. The problem I’m seeing is that to actually deploy these to the public you can’t use a regular $5/ month (or free) hosting service because you have to install these services on the server in ways that are not accessible in the average hosting scheme. So you either have to use a host that has MapServer installed (many of which look unreliable) or have a dedicated server or VPS. All of these options have a significant cost barrier ($30 - $200/month). I’m just doing this for fun. Are there any free or inexpensive ways to have your GIS services hosted? Or are there any products that install in a way that you don’t need to access the root structure of the server? I have tried OpenLayers and GeoExt but I don’t think a client side option will work for me because of the size of the datasets I am using. My base data will be vector data not WMS data (or something similar). I haven’t tried Google maps yet, but I will be looking into it. Also, any thought on using SVG for GIS purposes? Thanks

  • Simplification / optimization of GPS track

    - by GreyCat
    I've got a GPS track, produces by gpxlogger(1) (supplied as a client for gpsd). GPS receiver updates its coordinates every 1 second, gpxlogger's logic is very simple, it writes down location (lat, lon, ele) and a timestamp (time) received from GPS every n seconds (n = 3 in my case). After writing down a several hours worth of track, gpxlogger saves several megabyte long GPX file that includes several thousands of points. Afterwards, I try to plot this track on a map and use it with OpenLayers. It works, but several thousands of points make using the map a sloppy and slow experience. I understand that having several thousands of points of suboptimal. There are myriads of points that can be deleted without losing almost anything: when there are several points making up roughly the straight line and we're moving with the same constant speed between them, we can just leave the first and the last point and throw anything else. I thought of using gpsbabel for such track simplification / optimization job, but, alas, it's simplification filter works only with routes, i.e. analyzing only geometrical shape of path, without timestamps (i.e. not checking that the speed was roughly constant). Is there some ready-made utility / library / algorithm available to optimize tracks? Or may be I'm missing some clever option with gpsbabel?

  • Asset Pipeline acting up

    - by Abram
    Ok, so my asset pipeline has suddenly started acting up on my development machine. JS functions that previously worked are now throwing "not a function" errors.. I know I must be doing something wrong. A minute ago the datatables jquery function was working, then it was throwing an error, then it was working, and now it's not working or throwing an error. Here is my application.js //= require jquery //= require jquery-ui //= require jquery_ujs //= require_self //= require_tree . //= require dataTables/jquery.dataTables //= require dataTables/jquery.dataTables.bootstrap //= require bootstrap //= require bootstrap-tooltip //= require bootstrap-popover //= require bootstrap-tab //= require bootstrap-modal //= require bootstrap-alert //= require bootstrap-dropdown //= require jquery.ui.addresspicker //= require raty //= require jquery.alphanumeric //= require jquery.formrestrict //= require select2 //= require chosen/chosen.jquery //= require highcharts //= require jquery.lazyload Here is some of my layout header: <%= stylesheet_link_tag "application", media: "all" %> <%= yield(:scripthead) %> <%= javascript_include_tag "application" %> <%= csrf_meta_tags %> <%= yield(:head) %> Above I am using the yield to load up online scripts from google as they're only needed on some pages, and generally slow down the site if included in the application layout. I tried removing the yield but things were still broken, even after clearing the browser cache and running rake assets:clean (just to be on the safe side). Here's what shows up between CSS and metatags (for a page with nothin in the yield scripthead): <script src="/assets/jquery.js?body=1" type="text/javascript"></script> <script src="/assets/jquery-ui.js?body=1" type="text/javascript"></script> <script src="/assets/jquery_ujs.js?body=1" type="text/javascript"></script> <script src="/assets/application.js?body=1" type="text/javascript"></script> <script src="/assets/aidmodels.js?body=1" type="text/javascript"></script> <script src="/assets/audio.js?body=1" type="text/javascript"></script> <script src="/assets/bootstrap-alert.js?body=1" type="text/javascript"></script> <script src="/assets/bootstrap-dropdown.js?body=1" type="text/javascript"></script> <script src="/assets/bootstrap-modal.js?body=1" type="text/javascript"></script> <script src="/assets/bootstrap-popover.js?body=1" type="text/javascript"></script> <script src="/assets/bootstrap-tab.js?body=1" type="text/javascript"></script> <script src="/assets/bootstrap-tooltip.js?body=1" type="text/javascript"></script> <script src="/assets/branches.js?body=1" type="text/javascript"></script> <script src="/assets/charts.js?body=1" type="text/javascript"></script> <script src="/assets/chosen/backup_chosen.jquery.js?body=1" type="text/javascript"></script> <script src="/assets/chosen/chosen.jquery.js?body=1" type="text/javascript"></script> <script src="/assets/consumers.js?body=1" type="text/javascript"></script> <script src="/assets/dispensers.js?body=1" type="text/javascript"></script> <script src="/assets/favorites.js?body=1" type="text/javascript"></script> <script src="/assets/features.js?body=1" type="text/javascript"></script> <script src="/assets/generic_styles.js?body=1" type="text/javascript"></script> <script src="/assets/gmaps4rails/gmaps4rails.base.js?body=1" type="text/javascript"></script> <script src="/assets/gmaps4rails/gmaps4rails.bing.js?body=1" type="text/javascript"></script> <script src="/assets/gmaps4rails/gmaps4rails.googlemaps.js?body=1" type="text/javascript"></script> <script src="/assets/gmaps4rails/gmaps4rails.mapquest.js?body=1" type="text/javascript"></script> <script src="/assets/gmaps4rails/gmaps4rails.openlayers.js?body=1" type="text/javascript"></script> <script src="/assets/highcharts.js?body=1" type="text/javascript"></script> <script src="/assets/jquery-ui-1.8.18.custom.min.js?body=1" type="text/javascript"></script> <script src="/assets/jquery.alphanumeric.js?body=1" type="text/javascript"></script> <script src="/assets/jquery.formrestrict.js?body=1" type="text/javascript"></script> <script src="/assets/jquery.lazyload.js?body=1" type="text/javascript"></script> <script src="/assets/jquery.ui.addresspicker.js?body=1" type="text/javascript"></script> <script src="/assets/likes.js?body=1" type="text/javascript"></script> <script src="/assets/messages.js?body=1" type="text/javascript"></script> <script src="/assets/overalls.js?body=1" type="text/javascript"></script> <script src="/assets/pages.js?body=1" type="text/javascript"></script> <script src="/assets/questions.js?body=1" type="text/javascript"></script> <script src="/assets/raty.js?body=1" type="text/javascript"></script> <script src="/assets/reviews.js?body=1" type="text/javascript"></script> <script src="/assets/sessions.js?body=1" type="text/javascript"></script> <script src="/assets/styles.js?body=1" type="text/javascript"></script> <script src="/assets/tickets.js?body=1" type="text/javascript"></script> <script src="/assets/universities.js?body=1" type="text/javascript"></script> <script src="/assets/users.js?body=1" type="text/javascript"></script> <script src="/assets/dataTables/jquery.dataTables.js?body=1" type="text/javascript"></script> <script src="/assets/dataTables/jquery.dataTables.bootstrap.js?body=1" type="text/javascript"></script> <script src="/assets/bootstrap-transition.js?body=1" type="text/javascript"></script> <script src="/assets/bootstrap-affix.js?body=1" type="text/javascript"></script> <script src="/assets/bootstrap-button.js?body=1" type="text/javascript"></script> <script src="/assets/bootstrap-carousel.js?body=1" type="text/javascript"></script> <script src="/assets/bootstrap-collapse.js?body=1" type="text/javascript"></script> <script src="/assets/bootstrap-scrollspy.js?body=1" type="text/javascript"></script> <script src="/assets/bootstrap-typeahead.js?body=1" type="text/javascript"></script> <script src="/assets/bootstrap.js?body=1" type="text/javascript"></script> <script src="/assets/select2.js?body=1" type="text/javascript"></script> From application.rb: config.assets.initialize_on_precompile = false # Enable the asset pipeline config.assets.enabled = true config.action_controller.assets_dir = "#{File.dirname(File.dirname(__FILE__))}/public" # Version of your assets, change this if you want to expire all your assets config.assets.version = '1.0' I'm sorry, I'm not sure what else to include to help with this puzzle, but any advise would be appreciated.
