AiGIS is a 3D GIS designed for analysis on exploration data of irregular-shaped small bodies. The shape of a target body is represented by a polygon model, and geographic information is associated with polygons of the model. AiGIS can visualize and manipulate the shape model and map data on it.

Data set structure

Minimum contents of the data set directory for AiGIS are as follows:

The Shapemodel directory is usually used to place shape models and gird data, but they can be placed outside this directory. Files in MapData and MapDataHigh directories are assumed and try to load as map data for the SHAPE and SHAPEHIGH models respectively.

Items in AiGIS_setting.txt

All items in AiGIS_setting.txt are described in KEY = VALUE style. Multiple VALUES may be assigned in the following format

AiGIS was originally developed as a research project by students at the University of Aizu.

The project is supported by JSPS KAKENHI Grant Number 17K05639, "FY2017-19 Coordination Funds for Promoting AeroSpace Utilizaiton MEXT, Japan", and a collaborative research between JLPEDA/JAXA and the University of Aizu.

Aizu Laboratory, Inc. supports development and maintenance of the software.
