r <br /> Unmappable Sites <br /> ' A limitation of many records of governmental databases is incomplete or incorrect address information. <br /> Without proper addresses, it is more difficult to locate and map these saes. <br /> ' Instead of leaving these potentially important sites out of the manually geocoded EcoSearch report, we <br /> implement a painstaking manual geocoding strategy aimed at plotting these unmappable sites by looking <br /> ' at zip codes, city names, and county names identified with the radius around your study site. The zip <br /> codes, cities, and counties searched are identified on the EcoSearch Statistical Overview page. <br /> ' Our sophisticated mapping software, enhanced TIGER street maps, and address correction database <br /> processing methods find and plot most environmental sites. We then perform manual geocoding, plotting <br /> those sites the computer fails to find using a variety of resources. These include using our in-house <br /> collection of paper maps, directories,cross-referencing database information, and calling post offices, local <br /> government, or the sites themselves to accurately locate environmental records. We also correct obvious <br /> ' TIGER street map errors and omissions. <br /> ' This effort at manual geocoding results in a short or non-existant orphan/unmappable list and increases <br /> accuracy and reliability of the data in our reports. The EcoSearch Instant Online and Preview reports take <br /> advantage of all previous geocoding work that has been done providing the highest quality report virtually <br /> instantaneously. The potential remains that an order can be placed in an area which has not been worked, <br /> thus resulting in more unmappables than typically associated with an EcoSearch report. <br /> The limited number of sites which could not be reasonably found through our geocoding strategy are <br /> presented in this section for further review to assess their impact on your study site. <br /> After the summary unmappable site information, the detailed data follows. <br /> r <br /> i <br /> ' EcoSearch Report ID: 2786-3801 <br /> Environmental Date of Report: March 21,2002 <br /> Resources,Inc.
