软件介绍
======Karta 是一个开源的 Python 地理空间分析包，可简化处理矢量和栅格数据。
创建矢量地理空间：
point = Point((-130.0, 52.0), crs=LonLatWGS84)
line = read_geojson("linedata.json")
polygon = Polygon([(-515005.78, -1301130.53),
(-579174.89, -1282271.94),
(-542977.83, -1221147.82),
(-437864.05, -1251641.55),
(-438160.72, -1252421.48),
(-437961.28, -1285314.00)],
crs=NSIDCNorth)执行简单查询：
point2 = Point((-25.0, 48.0), crs=LonLatWGS84)
point.distance(point2) # Distance in geographical units
line.intersects(polygon) # True or False
ch = polygon.convex_hull() # Returns a new polygon
ch.to_shapefile("poly.shp")加载可操作的格栅数据：
grid = read_gtiff("landsat_scene.tif") # Leverages GDAL
grid.profile(line) # Collect data along a line
grid.resample(500.0, 500.0) # Return a grid resampled at a new resolution
