This is an ArcGIS toolbox for landscape limnology created from a collection of Python script tools. It was used to create the LAGOS-NE database and is currently being updated in 2017 and 2018 for the creation of the LAGOS-US database.

This toolbox was created with ArcGIS 10.1. It is being maintained in ArcGIS 10.3. It may work for other versions of ArcGIS.

Release v1.0 corresponds to the methods documented in the following manuscript:

Soranno, P. A., Bissell, E. G., Cheruvelil, K. S., Christel, S. T., Collins, S. M., Fergus, C. E., ... & Scott, C. E. (2015). Building a multi-scaled geospatial temporal ecology database from disparate data sources: fostering open science and data reuse. GigaScience, 4(1), 28.

• Spatial Analyst extension (some tools)
• RivEX software (proprietary) to create the input (rivers with Strahler order assignment) to the Lake Order Tool.
• While some steps in our workflow at Michigan State University are conducted in a supercomputing environment (ie Taudem pitremove & d8flowdir were ported to RHEL to get the data processed faster), you can do these steps on a workstation easily enough with ESRI tools or with the Taudem tool suite.
