问题 TLDR I want to refresh a layer on a timer so it plots the new kml data (like update-link / network link) So far I have tried action function as follows: function RefreshKMLData(layer) { layer.loaded = false; layer.setVisibility(true); layer.redraw({ force: true }); } set interval of the function: window.setInterval(RefreshKMLData, 5000, KMLLAYER); the layer itself: var KMLLAYER = new OpenLayers.Layer.Vector("MYKMLLAYER", { projection: new OpenLayers.Projection("EPSG:4326"), strategies: [new

Google Maps kml files

阅读更多关于 Google Maps kml files

If I use an embeded google map in my website, will the data contained in an kml displayed be publicly viewable? Will it be possible for the user to access just the data displayed (i.e., not the user interface) or would I have to provide that separately? If you load your KML through the API, with GGeoXml(), (V2), or KmlLayer(), (V3), then your data needs to be in a public server because it is parsed by Google's servers and they need to be able to get to it. If you load it with a third party extension then you can keep it private. Third party extensions that can load and parse KML data are

Adding a KML layer to an Android maps application

阅读更多关于 Adding a KML layer to an Android maps application

I have been starting out in the world of Android development recently and I am working on an application which shows a map using the Google API SDK, it is pretty much the original example but edited a little bit. It works a treat but I wish to do more with it. My question is: How do you add a KML layer to this? I've not found many examples out there and none of them are very clear. I know how to do this with Javascript on websites but not in android. Can anyone help? Google added a support to KML recently in its utility lib. You can instantiate a KMLLayer as below: KmlLayer layer = new

Java API for KML (JAK) embedding images in kmz files

阅读更多关于 Java API for KML (JAK) embedding images in kmz files

Is there a way to just add an image file into a kmz file using Java API for KML (JAK)? I can create a kml file with no problem, but I'm trying to just embed a resources (such as an images folder with some image files), but the marshalAsKmz method takes only Kml objects as additional files, so I can't figure out how to just include extra images. I've been using JAK for over a year on a project. I use it to create the KML, then I marshal it as just plain KML (not KMZ). I created a separate utility class that uses the Java SE 'Zip' classes to manually create the KMZ. It works just fine. A KMZ is

问题 Is there a simple way to set up checkboxes to toggle (on/off) KML layers for Google Maps v3? I've come across these articles, but none of them have worked for me. 回答1: Sorry my article didn't work for you, it is a little dated.

Does the Android API support KML files?

阅读更多关于 Does the Android API support KML files?

Is there a way in Android to load KML files from Google Earth into a map widget? Specifically I am looking to load saved shapes created in Google Earth overtop a map widget as easily as possible. Has anybody ever tried this before? It is an old question but this answer might be of some use if someone happens to stumble upon it. Do you mean to add the kml file onto a mapfragment inside an app programmatically? If so, you can use this method. private void loadKml(File file) { try( InputStream inputstream = new FileInputStream(file) ) { // Set kmllayer to map // map is a GoogleMap, context is the

Nesting KMZ files

阅读更多关于 Nesting KMZ files

Is it possible to create one KMZ file that is composed of several smaller KMZ files? I would prefer to not have to manually merge the actual KML entities, but I will if that's the only option. A KMZ file can have any number of inner KML files (NOT KMZ files). But the first entry in the KMZ file must be the root KML file (typically named doc.kml ), which may include network links with references to other KML or KMZ files. Several inner KML files, for example, could reference a shared style (in another KML file) via relative URLs. The inner KML files can nest to any level of depth to other KML
