This is a well-written proposal, but does not make a compelling case about why information should not be handled by PTAGIS. Has PTAGIS been asked to track this additional information? It seems this data could easily be incorporated into PTAGIS with some coordination with the project sponsor. Modification of the existing data base system (PTAGIS) is likely a more efficient option to improve data accessibility and to add spatial considerations. The ISRP is concerned about duplication of effort with this proposed project. The parties need to get together.
