The odd solution to the intersection of two polygon in the GPS fence and the odd solution to the gps fencePreface The area of the origin area measured by the GPS measuring instrument is then submitted to the system. The system needs to check whether

Cédric Bignon:Let's note the Points points of the polygon (where to Points[0] == Points[Points.Count - 1] close the polygon).The idea behind the next methods are to split the polygon into triangles (the area is the sum of all triangle areas).

Gmap.net is great and powerful, free, cross platform, open source. NET control. Enable use routing, geocoding, directions and maps from Coogle, Yahoo!, Bing, OpenStreetMap, ArcGIS, Pergo, Sigpac, Yandex , mapy.cz, maps.lt, ikarte.lv, Nearmap, Ovimap,

There are a lot of classmates recently. Ask me questions about honeycomb polygons. That is, the hexagon, which is the following stuff:General question and answer modes such as the following:Pro Q: What is the tool in ArcGIS that can do this

　Recently learned computer graphics, wrote a polygon scan conversion algorithm, posted out to share; MFC is not too clear, mainly using the OnDraw function ... Please advise ... void Cpolyfillview::ondraw (cdc* pDC) { cpolyfilldoc* PDoc =

Improved scanning-line filling algorithm The principle and implementation of the scan line filling algorithm is simple, but the requirement for storage space is high because it maintains both the active side table (AET) and the New Edge table (NET).

1. Straight Line Generation algorithmThe so-called entity generation refers to the transformation of the parameter representation of the finished entity (as specified by the user of the graphics package) to the bitmap representation (the

The area of the convex polygon and seems to have a lot of way, the Net has O (N^2LOGN) algorithm, the nest will only O (N^3LOGN) scan line violence (seems to be able to do O (n^3) is to solve. The endpoints of all triangles and intersections are

A Three ways to Route events/policies (Bubbling direct tunneling)Routed events in WPF are passed along VisualTree and are used to invoke handlers on various listeners on the application's element tree.(1) Bubbling, this event is handled from the

There is often a need to merge all the intersecting Polygon into one. No available tools are found in arctoolbox. (Merge, union is not this function. Dissolve is a combination of attributes. So I want to use dissolve. Set a field to be merged and
