# MakeGridLine.jar
MakeGridLine.jar is a utility to generate latitude-longitude grid data for AiGIS from a shape model.

## Usage
```
java -jar MakeGridLine.jar Shape.obj
```
will generate a pair of grid files, grid_white.txt and grid_red.txt, with the grid spacing of 10 deg. are generated. grid_red.txt contains grid data for the eauator and the primal meridian.

```
java -jar MakeGridLine.jar Shape.obj GRID_SPACING CALC_INTERVAL LAT_MIN LAT_MAX LON_MIN LON_MAX
```
will generate a grid file covering the designated latitude and longitude range with GRID_SPACING. CALC_INTERVAL specifies the resolution to obtain intersections on the surface of the shape model. 

## System requirement
MakeGridLine.jar requires Java 1.8 environment.
