Wahkiakum County Mapping Project

submitted by Dan Kistler, 360-795-3242


To determine the minimum mapping standards for mapping in a PSAP.


Determine the usefulness of Electronic Mapping to the E9-1-1 mission.. Determine the location and usefulness of existing mapping and layers i.e., streets, monuments, buildings, waterways





Known Errors Made:

Must use correct MSAG when naming streets on MapInfo. Used existing County/State Maps with incorrect naming.

Wish List:

Ability to fax map to Fire/Ambulance on E9-1-1 Call.


The project began on 9/7/95, in partnership with the E9-1-1 State Office, Allen Jakobitz. We established a timeline of about 6 months, to accommodate weather and other possible problems such as scheduling, etc.

The RFP process was completed about mid-October, 1996. The project and test plan was completed in November, and training in December. Data Collection began in January 1996.

There was a great deal of discussion concerning the number of layers that would be both needed and/or useful for 9-1-1 purposes, such as how to color code the different jurisdictions of area, streets, boundaries, hazards, markers, monuments, etc. Next, the determination of who already possessed such laying in current maps and data, (DNR, DCT, etc.).

Training on the MapInfo piece, MrGPS and MOM products was conducted in December. MrGPS is an add-in to MapInfo which we ran on a 486 laptop connected to a Trimble receiver and a real-time differential translator using the NavBeacon in Astoria, OR. During one storm, we consistently read 6 satellites and kept the link to Astoria while traveling up to 40 mph. All of our results were reproducible. Traveling the same route a second time resulted in a duplicate line. The estimated accuracy is 6-10 feet. 

The collection of data is very easy. When actually mapping, the collector will stop and change the street name each time a new street is entered. A limitation of MrGPS is that is uses a RAM drive and after about 10-15 minutes, it must be saved, reset and restarted. While this was not a major problem, it was soon corrected by the addition of RAM to the laptop.

The purpose of the mapping is to provide a visual display to the telecommunicator of the location of the call. Immediately the ALI will be sent from the Nine One One, Inc. CAD to MapInfo. A look-up of the address will be made If the street name matches exactly and the number falls within that street range, the location will be displayed. If there is no match, an attempt will be made for a second match. No exact match will result in an error message. The dispatcher ill record every mismatch and then MapInfo or ALI will corrected.

The Map Operation Manager (MOM) was also taught. This is also a MapInfo add-in. It allows for specific addressing activities, including the assignment of street names and segment number ranges. It allows for the creation of ESN territories as well as their assignment. It also automatically creates a MSAG. All of the activities were straight forward.

Cavenham Forest Industries agreed to provide a GIS layer of all their logging roads. They create about 20 new miles a year and would provide updates. The state will purchase DNR’s transportation and hydrology layers to compare to the Wahkiakum County CAD maps to compare to the actual GPS collected data. The point is to determine if there are any pre-existing maps that can be used as a starting point for this project.

Since this project began, Nine One One, Inc. has provided the interface necessary to bring the map and location onto the CAD screen upon receipt of a 9-1-1 call. The flaw in the system is that it must be done manually. Currently, the map is not faxable with the 9-1-1 call to the Fire/Ambulance companies as is the ASCII text.

An on-going project is the adjustments to the maps and identification of roads not collected for whatever reason. Many new private roads are being created as a result of 9-1-1 standardization. MOM makes this quite easy, the problem is scheduling when we already short-handed.

All in all the system works well and I believe it is an asset to our E9-1-1 system.


Wireless Update

submitted by Jane Bissonnette, 206-674-1030

The Cellular Telecommunications Industry Association (CTIA) hosted a one-day seminar on wireless 9-1-1 issues on January 15, 1997 in Washington, DC.

The morning sessions of the CTIA conference were comprised primarily of presentations by the three prominent trials that have taken place proving there are wireless 9-1-1 solutions that work. There was a single Phase I trial presentation which was our own Clark County, WA. Thera Bradshaw explained how working with US WEST and Proctor they were able to supply callback number and cell site information with no change to PSAP infrastructure including the CAMA interface. John Melcher gave a lively demonstration of the Houston trial which included being able to locate the wireless user to a significant level of accuracy. John believes they were very close if not able to meet the FCC Phase II requirement of 125 meters, 67% of the time. They are still preparing their official report. John’s primary messages were teamwork and caution regarding map accuracy. Introduction of inaccurate maps will amplify the imprecision inherently involved in locating wireless users. The third trial was presented by Bob Miller. It takes place in New Jersey using the same location technology, TruePosition. Both Bob and John use state-of-the-art SS7 signaling for their transport and customized their 9-1-1 networks specifically to support their trials. The bottom line is that these trials prove that the FCC order can be met in the time frames prescribed by the FCC.

The afternoon sessions were devoted to presentations by vendors that have solutions for wireless E9-1-1. They included:

  • Accucom – a location technology company with an Time Difference of Arrival application.
  • XYPOINT – which supplies location enhanced services for transporting ANI and cell site or X-Y within existing 9-1-1 infrastructure,
  • SCC – which supplies database services
  • CellTrax – a location technology which is based on Time of Arrival technology. Initially used to locate lightning strikes.
  • TruePosition – Time Difference of Arrival technology for locating wireless users. TruePosition was used in both the Harris County and New Jersey trials.
  • Tendler – attaches a GPS receiver to an existing wireless phone and transmits the X-Y coordinates over the voice channel to the 9-1-1 center.
  • KSI – Another Time Difference of Arrival company with tracking capability.

The final portion of the day was given to updates on wireless standards, discussion on geographic coordinates and whether or not to use latitude-longitude or UTM and a panel discussion to wrap up the day.

The conference was very well attended by wireless carriers and public safety. The final message was that meeting the FCC requirements is possible, has been proven in these trials but it takes team work.
