Here it is in 1887, just before Orange County was created the year after:
The Atlas of Historical County Boundaries allows you to explore how county boundaries have shifted throughout history. You can also download GIS shapefiles of polygons for each different configuration of a state’s counties or the entire United States, coded by date. Check it out!
The California Geologic Survey (CGS) Seismic Hazards Program has significantly updated two versions of its regulatory hazard zone map products. First, all GIS data files (in ESRI Shapefile format) for fault rupture, liquefaction and earthquake-induced landslide zones have been re-projected to California (Teale) Albers, in meters, with a North American Datum 1983. In addition, all GIS zone polygons now include attributes that provide the name of the 7.5-minute quadrangle, map release date(s), and links to zone reports and PDF maps. Active fault traces within earthquake fault zones have attributes for fault name and fault type. Continue reading
The Interdisciplinary Earth Data Alliance (IEDA) data facility aims to, “support, sustain, and advance the geosciences by providing data services for observational geoscience data from the ocean, earth, and polar sciences.” The IEDA, which is funded by the US National Science Foundation, is headed by staff at Columbia University’s Lamont-Doherty Earth Observatory. On this website, you will find a number of data repositories and data syntheses, which are collections of data sets with a shared area of investigation. Data repositories include information in the fields of Antarctic science, marine geology and geophysics, and geochronology. You can also download the free GeoMapApp, which is a free software tool for creating data visualization. Check it out!
Whether you are an ArcGIS Online subscriber or an ArcGIS Hub user, you can launch an open data site in 3 steps, which include configuring and designing the site and making it public. Check out ESRI’s post about it here.
The Los Angeles County Assessor has just released their 2016 tax roll parcels. The 2016 parcels (in a file geodatabase) with associated tax roll information can be downloaded at the Los Angeles County GIS Data Portal.
