Openlayers calls WMS
Openlayers:
Openlayers is an open-source JS framework used to implement Map Browsing effects and basic zoom and Pan functions in your browser. The map sources supported by openlayers include WMS, GoogleMap, kamap, and msvirtualearth. You can also use simple images as the source. openlayers provides many options.
WMS service:

After creating a scenario in cityengine, We need to export the created model (in 3DS and OBJ formats ).
You can select two export modes: Use File size limit and create one file per shape.
Use File Size Limit: export the selected model as an OBJ or 3DS file.
Createone file per shape: exports the model according to the shape. A 3DS or OBJ file is generated for the model generated by each shape.
Figure 1Export Method
Next we will discuss the naming of model files when exporting models using the cr

After six months of study and debugging, I finally wrote a simple GIS. On the ARM development board, I chose QT/Embedded 2.3.7 as the graphic development interface. I debugged the touch screen yesterday, finally, a little result is coming out. I'm very happy. I just published a message to celebrate it.
Many people ask me for code reference, but because it is a project, it cannot be used for reference. Sorry. In addition, if you need to find a refer

To be honest, since I posted this algorithm, I have never followed this article any more. So many of my friends did not see the message and replied in a timely manner. Here I say "sorry ".
This buffer algorithm is an algorithm used in our project. It is all written by myself based on my own paper. It is not well handled in many places, but it is basically common to deal with it, the buffer accuracy rate is still between 60%-80%. Because I have been busy working on projects, this algorithm has
