Because we do have a project on tourism, so it involves the map function. One of the tasks I received was to show a few designated sights on the map and add markers to the map.Our project is using Sogou map. The JS version number is used. If you are interested, you can refer to the Search Map API and Demo sample code.Adding markers to a map is a basic function of the map. This mark is called marker. Can be crossing from here on the Internet for marker class introduction.The basic steps to implem
JSON data is common and useful in Android, and JSON data is also supported in ArcGIS, and JSON and geometry can be converted to the data we want.One, geometry converted to JSON dataThis implementation is very simple, for example, when we convert a point to JSON, we also use the powerful class Geometryengine.Point point = new Point(113, 23); String json = GeometryEngine.geometryToJson(SpatialReference.create(SpatialReference.WKID_WGS84), point); Log.w("TAG", "json===" + json);The result of

Since I have time today, I will write a few more blog posts, but also for tomorrow to go out to play a good relaxing.
As the comrades in the field of GIs know, the traditional Douglas-poke algorithms are recursive implementations. However, sometimes the recursive hierarchy is too deep, there will be stack overflow situation. In this paper, a non recursive algorithm is introduced.
To change the recursive algorithm to a non recursive algorithm, it is ge

Three years ago, listening to the then brother recommended, bought Chiang waves of a book on the framework of GIS plug-ins. At that time while reading one of the examples of the complete realization of the case, the profit is shallow. Later, as a result of the project needs, also made a plug-in C/s system, with the MEF provided by Microsoft's framework. In this system, the communication of the Plug-ins and plug-ins not covered by Chiang's waves in his
As a GIS developer, no algorithm, too easy to be despised, so must seriously learn the algorithm, and constantly summed up, very grateful to the beginning of the entry, met a serious master. Good memory is better than bad writing, some basic geometric algorithms recorded, for follow-up inspection.
