**GIS Cup Sample Data Set:** Download

The sample data set provided for the GIS Cup contains 12 files: 4 input files and 8 output files.

**Input Files**

In the sample dataset, there exist four input files, described as follows:

`points500.txt`

: this file contains a set of 500 points such that each point may have a different spatial location at different sequence number.`points1000.txt`

: this file contains a set of 1000 points such that each point may have a different spatial location at different sequence number.`polys10.txt`

: this file contains a set of 10 polygons such that each polygon may have a different spatial location and different shape at differet sequence number.`polys15.txt`

: this file contains a set of 15 polygons such that each polygon may have a different spatial location and different shape at differet sequence number.**Output Files**

In the sample dataset, there exist eight output files, described as follows:

`polys10_points500_INSIDE_out`

: this file contains the expected output from applying the "INSIDE" predicate on the points in `points500.txt`

and the polygons in `polys10.txt`

.`polys10_points500_WITHIN_1000_out`

: this file contains the expected output from applying the "WITHIN 1000" predicate on the points in `points500.txt`

and the polygons in `polys10.txt`

.`polys10_points1000_INSIDE_out`

: this file contains the expected output from applying the "INSIDE" predicate on the points in `points1000.txt`

and the polygons in `polys10.txt`

.`polys10_points1000_WITHIN_1000_out`

: this file contains the expected output from applying the "WITHIN 1000" predicate on the points in `points1000.txt`

and the polygons in `polys10.txt`

.`polys15_points500_INSIDE_out`

: this file contains the expected output from applying the "INSIDE" predicate on the points in `points500.txt`

and the polygons in `polys15.txt`

.`polys15_points500_WITHIN_1000_out`

: this file contains the expected output from applying the "WITHIN 1000" predicate on the points in `points500.txt`

and the polygons in `polys15.txt`

.`polys15_points1000_INSIDE_out`

: this file contains the expected output from applying the "INSIDE" predicate on the points in `points1000.txt`

and the polygons in `polys15.txt`

.`polys15_points1000_WITHIN_1000_out`

: this file contains the expected output from applying the "WITHIN 1000" predicate on the points in `points1000.txt`

and the polygons in `polys15.txt`
