Use of ARC for geospatial analysis

WIP, working with Forestry and iGEP to flesh out relevant examples …

Introduction

Geospatial analysis problems often require specialized software and data considerations. Here, we lay out some common softwares and give examples of use specific to the geospatial community. We will be forward looking and devote this page to TinkerCliffs and Infer only.

Data location

TinkerCliffs has two main storage systems:

• /projects served by GPFS storage

• /scratch served by VAST storage

In addition, each compute node has local disk and RAM mounted as a volume.

Generally, data should be moved to the local node for the compute nodes during the computation and results saved, then transfered back to main ARC storage. To see what local storage is available on each compute node, type env | grep TMP. This will list the environment variables you can use to access the different storage locations.

Common software and availability

• Python

• Julia

• R

• qGIS
