- Hello,
-
- I'm going to write a program to view map data efficiently (vectors, areas,
- symbols etc). I don't want to use a fully configured GIS program.
-
- The question is to find a suitable library/toolkit to base such an utility
- on. The library must handle vectors, filled polygons, raster and vector
- symbols. It should be possible to use vector symbols to draw lines for
- example. The viewer will be 2D, but 3D might be needed later. I want
- to use my own datastructure for storing map objects (i.e attributes to
- a land area object describes the color and fillstyle for the area).
-
- I'm looking for "the best" library for this, i.e the right tradeoff between
- speed/flexibility/coding complexity. I'm thinking in the lines of
- Xlib, PEXlib, OpenGL, PHIGS, GKS, Uniras, ???
-
- Any recommendations/experiences with these or other ?
-
- thanx,
-
