GIS Consultant for Getty Conservation Institute

The Getty Conservation Institute (GCI) is seeking a detail-oriented freelance consultant to assist in the review and editing of geospatial data from a project focused on the mapping of an archaeological site in Cyprus for purposes of conservation and management and archaeological research. Interested consultants must be proficient in the use of ESRI ArcGIS software, including with ESRI geodatabases, and preferably with a working knowledge of AutoCAD and Microsoft Access.  The work is expected to be carried out January 2019 through March 2019, to be up to a maximum of 40 hours per month, with potential for additional work to follow. It will require periodic visits to the GCI at the Getty Center in Los Angeles to discuss work deliverables.  Responsibilities will include checking primarily GIS, but potentially also AutoCAD, data with respect to adherence with specifications and making any necessary corrections, producing map and potentially AutoCAD layouts needed for project reports, and adding attribute information to geodatabase and potentially Access files and building related queries. Pay rate of $20/hour.

Moving To PostgreSQL (Part 3)

Welcome back!  Last time in Part 2 we configured PostgresSQL on a Linux server.  Now it is finally time to create an Enterprise Geodatabase in PostgreSQL.

Keycodes File

You now need to find your keycodes file.  This file was created when ArcGIS Server was installed on one of your servers.  This file is written to \Program Files\ESRI\License<release#>\sysgen folder on Windows servers and /arcgis/server/framework/runtime/.wine/drive_c/Program Files/ESRI/License<release#>/sysgen on Linux. Copy the keycodes file to a computer that you run ArcGIS Desktop on.  You will need access to it when creating the Enterprise Geodatabase.  Continue reading

Moving To PostgreSQL (Part 2)

Welcome back!  Last time in Part 1 we installed PostgresSQL on a Linux server.  Now we need to do a few things to get it ready so we can create an Enterprise Geodatabase in it.

Postgres User

When PostgreSQL was installed, a postgres user was created.  The postgres user is the default “superuser” to the PostgreSQL database.  Right now the postgres user password is unknown to you.  You must change it in Linux and in the PostgreSQL database.

Log back in to the Linux server and at the Linux prompt, use the passwd command to change the postgres user password.  You might need to use the sudo command with it for it to work.  Continue reading

Quantitative Map Literacy

Quantitative map literacy can be seen as a cross between map literacy and quantitative literacy.  Quantitative map literacy includes the concepts and skills required to accurately read, use, interpret, and understand the quantitative information embedded in a geospatial representation of data on a geographic background.
