Analyzing Real Estate Statistics using GIS

Interwest’s GIS team recently began working with JohnBurns Real Estate Consulting, a consulting company that provides housing research and consulting to builders, lenders, investors, and building product manufacturers.

As part of their services to their housing industry clients, John Burns Real Estate Consulting provides maps and analysis of metro area statistics throughout the United States.  Their consultants had been using Microsoft Map Point and Adobe Photoshop to create maps, but needed a more robust system that allowed them to get the clean look they were after without the effort involved in scrubbing the map in Photoshop.

Interwest’s GIS team installed Esri’s ArcGIS for Desktop, created a geodatabase with all of their geographic and demographic data, and created a series of map templates to demonstrate building industry statistics such as job growth, unemployment rates, affordability, resale price growth, foreclosures, pre-forclosures, and home sales growth.  Now they are able to quickly create data driven maps that focus on the content their clients are seeking to make housing industry decisions.

Interwest built models that will automatically process the data from the company’s SQL database into the geodatabase which updates existing maps with the current month’s data, saving the consultants a lot of time each month.

Strengthening Pavement Management Planning with GIS

A Pavement Management Program (PMP) provides a public agency with the maintenance history, current pavement condition index (PCI) and a plan for the future update of the public streets it maintains.  Agencies perform maintenance on streets each year as funds are available. 

Interwest works with our public agency clients to strengthen their PMP programs using GIS and pavement management software. Interwest has experience implementing the Metropolitan Transportation Commision's StreetSaver PMP for several clients including The City of Eastvale, The City of Bell, and the City of Wildomar.  The GIS component is an integral part of the PMP. 

  • Direct visual display and connection with the data showing existing or future conditions of pavements
  • A planning tool for staff and management in planning projects in their City.
  • Exhibits and maps for Engineering and construction contract bid documents, public outreach information, and/or for presentation to Council.
  • Provides supportive documents for securing grant funds
  • Develop a list of pavement areas recommended for maintenance and analyze the impact of various budget scenarios.

Using Esri’s ArcGIS for Desktop, the GIS team created various maps showing the pavement condition of all of the streets and which streets would be upgraded in each fiscal year for the next 5 years.  The ability to see pavement condition and future projects on a map display is a great help for project engineers

Interwest Can:
  • Acquire street data from counties, council of governments, or other local sources
  • Track road conditions from the field on tablets, phones, and other mobile devices 
  • Analyze pavement condition ratings and degradation over time, so agencies can make plans over the next 5 years regarding which roads need maintenance
  • Create a plan for budgeting the repairs and tracking the type of road rehabilitation that is needed allowing the agencies to coordinate repairs geographically to save time servicing one geographic region at a time
  • Create various maps showing the pavement condition of all of the streets and which streets would be upgraded in each fiscal year.

GIS ADA Compliance Curb Ramp Project

Interwest’s GIS Team created an ArcGIS Online application that was used in the field to collect individual curb ramp location attribute information.  The goal of the project was to create an improvement plan for the City of Bell to repair curb ramps over several fiscal years depending on priority. The plan was used to help the city with its Americans with Disabilities Act (ADA) Compliance efforts.

The GIS team met with City of Bell staff to determine a list of attributes required for the project, created a shell geodatabase with these attributes in ArcGIS Server to facilitate direct live edits into the city production data set, and brought the geodatabases together with aerial photos provided by Esri’s Bing Basemaps.  The GIS team systematically reviewed the entire city, creating a point location for each curb ramp, then created an ArcGIS Online application to be used in the field for data collection.

A field inspector visited each location and updated the condition of the curb ramps using ArcGIS Online on a 3G enabled Apple iPad.  These updates were available in real time to GIS staff at the office.

After the data collection phase was complete, the GIS team worked with project engineers to determine location priorities such as high traffic areas and physical condition of the curb ramp. After all the priorities were determined a Map Series was made to display these priorities and create an improvement plan across several fiscal years.

The data was brought into ArcMap to create maps for a public meeting to showcase the city's plans for future ramp improvements.  An ADA Transition plan was created for each fiscal year; additional maps were created to show the public the plans for the current year.
