Edit and generate spatial datasets with the help of this tool. SkyJUMP is an open source GIS program for the creation and use of facility maps and data on small to medium sized areas such as cities or military bases. It is written in Java and based on JUMP from Vivid Solutions.

JUMP includes:
1. The JUMP Workbench, an extensible, interactive GUI for visualizing and manipulating spatial features with geometry and attributes,
2. An API for performing basic spatial data manipulation tasks, including data I/O, spatial indexing, spatial QA tools, spatial analysis functions, and more.

The JUMP Workbench is a graphical user interface (GUI) that can be used to visualize and manipulate spatial datasets. It exposes the functionality of the JCS Conflation Suite (including functions such as warping and conflation) and allows it to be applied to spatial datasets in a convenient and intuitive way.
