GIS Solutions

The eGIS Group provides support to many departments with additional services that go beyond the scope of the standard GIS Services, including custom map creation, GIS application development, geographic analysis, support of in-house applications, and advanced training. Requests are made through the ISD Service Request (see Attachment E.1 for example) and sent to your eGIS Representative or to the GIS Section Manager.

Custom maps

The eGIS Group can assist in the creation of aesthetic or informational maps and in a variety of sizes for all County departments. Maps can show trends, intensity, hot spots, and other useful information that may not be clearly visible from looking at data tables. If your department does not have an in-house mapping expertise and infrastructure, the ISD eGIS Group can create maps for you.

The eGIS Group can also create ArcMap templates pre-loaded with base maps and your department-specific datasets for your staff to use. This goal here is give your staff a head start into using GIS without searching through all the folders to find relevant spatial data.

The eGIS group has two color plotters (HP Designjets 500ps and Z6100ps) in house that can print up to 60 inches in width (length can vary). The printing of maps are at an additional cost. The eGIS Group is not responsible for the physical service of hanging maps on your walls – please contact your Department’s Facilities Operations Service.

Custom scripts and tools

The eGIS Group has programmers that can create custom scripts and tools for your department GIS needs. A GIS function that you are looking for may not be available in the toolbox or there are too many complex steps involved in getting the answer you need. Therefore, a script is needed to add specific functionality to your application, geoprocessing, or expedite data analysis. Scripts and tools can be written in python or .NET and can be reused by other departments, thereby saving time on many GIS tasks commonly used across the County.

For sample scripts and tools, see http://egis3.lacounty.gov/GISSolutions/ScriptsToolsSamples.html

Analysis and Research

The use of GIS promotes spatial knowledge, awareness, and increased understanding of the social or physical phenomenon being studied. GIS can help us explore spatial trends in data that may not be clearly visible. The eGIS group can perform spatial analysis on your datasets to discover relationships, patterns, and trends and results are visually displayed and organized on a map.

Examples:

  • Topological and geographic properties can be utilized to view service trends to help efficiently distribute services and resources.
  • Forecasts of detailed population characteristics including income, employment, migration trends, etc. at the regional, county, and census tract levels
  • Examine the dependence of one variable on one or more independent variables
  • Track the rate of a disease spreading and predict areas that will soon be impacted

If you are interested in this type of service or would like more information, email eGIS@isd.lacounty.gov.

Application development

GIS technologies have been applied to diverse fields to assist professionals in collecting spatial data, analyzing data, and mapping the results. Developers within the eGIS group can build or customize your own web application to work with your GIS services, workflows, and datasets. Custom GIS application services include:

  • Integrated mapping for websites, mobile devices, or lobby kiosks
  • Identity matching capabilities
  • Decision-making analysis and tools
  • Improved functionality including Bing Maps, Google and Esri APIs map controls and services

For eGIS department members, applications will be hosted on eGIS production servers at no extra cost.

If you are interested in this type of service or would like more information, email eGIS@isd.lacounty.gov.

Service Level

The Enterprise GIS Group maintains a Service Level Agreement (SLA), which outlines the service levels, roles and responsibilities, a staff matrix, escalation procedures, and terms and conditions governing the use of and access to eGIS systems.

Details about the eGIS Training and Support Service Levels and staff responsibility matrix can be found in the relevant section in the SLA.
