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

The main window under Python can be defined as follows:def start (self):#self. Project = Project ("temp")#self.

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. 1, Vector concept: If the end of a line segment has a sequence of points, called a directed segment, if there is a point to the beginning of the line segmen

In the twinkling of an eye, my junior year has arrived, but the number of courses for this semester has been surprisingly small. I don't know if it was because I took too much credits or the school arrangement. Under such circumstances, I decided to

Geospatial Relationship Analysis of geographic information mainly includes the degree of closeness(Proximity) analysis, overlay analysis, network analysis, etc. Buffer Zone Analysis is a kind of closeness analysis. A buffer zone is used to identify

Vector concept: If the endpoint of a line segment is ordered, we convert this line segment into a directed line segment ).If the start point P1 of the directed line P1P2 is at the coordinate origin, we can call it vector P2. Vector addition and

WKT (the well-known text) is a standard way in which the OpenGIS statement defines a space object. When we get this object, we need to parse it and draw it on our map. This article mainly describes how to use Java to parse it. Before parsing, you
