Converting Spatial Features to Map Projection

A system comprising:

• a spatial database to store a spatial feature and a projected coordinate system;
• and
• a computer processor to execute:
• a bisect module to:
• identify a spatial feature for projecting into a map projection;
• until a bisect threshold is satisfied for each of a plurality of line segments in the spatial feature:
• determine a bisect for each of the plurality of line segments;
• project each of the plurality of line segments into the map projection;
• and
• if the bisect threshold is not satisfied for a line segment of the plurality of line segments, divide the line segment into a plurality of subsegments, wherein the bisect threshold specifies an error distance for the line segment after projection;
• a projection module to project the modified spatial feature into the map projection to obtain a projected spatial feature;
• and
• a user interface module to:
• obtain a map request that specifies the map projection for a geographic area;
• and
• use the projected coordinate system that corresponds to the map projection to render the projected spatial feature in a spatial map

A non-transitory computer-readable medium comprising executable instructions for converting spatial features to a map projection, the instructions when executed causing a computer processor to:

• obtain a map request that specifies the map projection for a geographic area;
• identify a spatial feature for projecting into the map projection;
• until a bisect threshold is satisfied for each of a plurality of line segments in the spatial feature:
• determine a bisect for each of the plurality of line segments;
• project each of the plurality of line segments into the map projection;
• and
• if the bisect threshold is not satisfied for a line segment of the plurality of line segments, divide the line segment into a plurality of subsegments, wherein the bisect threshold specifies an error distance for the line segment after projection;
• project the modified spatial feature into the map projection to obtain a projected spatial feature;
• and
• use a polar coordinate system that corresponds to the map projection to render the projected spatial feature in a spatial map.
