EasyWMS Open Source WebGIS Projects

The DrivingDirection package (com.google.googlenav.DrivingDirection) is
removed since Android SDK 1.1. However, in this article, you will leanr
how to adopt driving direction function in
MapView object without the DrivingDirection package.

We can use the following url to create one static google map image:
"http://maps.google.com/staticmap?center=" + lat + "," + lng + "&format="
+ format + "&zoom=" + zoom + "&size=" + width + "x" + height + "&key=" + apiKey;

How could know the boundary coordinate information of this image?
What we know:
1. center latitude/longitude point where map centered on
2. map image's total pixel width/height
3. map zoom level.

In SUAS Map Server I used Openlayers to display WMS layers in EPSG:4326 SRS with Google Map, I found the WMS overlays are always be transformed, now i kown the reason. EPSG:4326 != EPSG:900913

The Extensible Stylesheet Language (XSL) includes both a transformation language and a formatting language. Each of these, naturally enough, is an XML application. The transformation language provides elements that define rules for how one XML document is transformed into another XML document.
The transformed XML document may use the markup and DTD of the original document, or it may use a completely different set of elements. In particular, it may use the elements defined by the second part of XSL, the formatting objects.

WMS Tiling Client Recommendation from OSGEO details extensions to and constraints on the OGC WMS 1.1.1 specification for the
purpose of (a) improving the quality and scalability of tiled maps, particularly
on the Web, and (b) making it possible to cache the results of tiled WMS
requests.

10, WMS Browser
Developed by Tom Vijlbrief, you can download this application from http://www.v7f.eu/
It is one OGC WMS map browser client with bluetooth and internal GPS support, if you have no GPS, it is a nice WMS client. You could give the WMS GetMap request url and browse the WMS map.

3, MapBrowser & MobileMap

I assumed that you have some basical Web Map Server knowledge to read this article, some terms I have not explained here to save time.

One year ago I developed MoWMSi as my Master Thesis and I began my programming way thanks to the mobile map viewer client for Web Map Server. Programers have always such feeling that you will find your old code very simple and crude after some period of time, yes, I found my old client has many problems in structure and a bad user capability to interact with WMS--it can not load the map from WMS dynamically!
