<br />F or the land outside th etro area, commercial and industrial zoning <br />designations that were to b 'ncluded in the land base were identified by TAC <br />members representing Lan ounty. Spatial queries were applied to the Lane <br />land use polygon coverage t arrive at the land base for the lands outside the <br />metro area. A detailed fio diagram is included at the end of this appendix that <br />documents all of the indivi al processes used to generate this file. <br /> <br />This process produced single GIS polygon file with new unique <br />identification attributes th t illbe used to populate the Access database. This <br />step is important for the n step of populating the database but will also be <br />instrumental for linking th esults of later database queries back to the GIS for <br />map display. <br /> <br />ECO designed a datab s structure that is simple and straightforward. The <br />goal was to create a struc r that can contain all of the attributes identified by <br />the partner agencies as val ble to this study and that can be effectively tied to <br />the outside GIS files, data es, and spreadsheets that will supply these <br />attributes. ECO will comp I this database as "snapshot" exports from outside <br />source datasets, but also d ument where and how static tables can later be <br />replaced with live, dynamO queries to their source datasets. In addition, this <br />structure creates a reposit for new data, identified by the partner agencies as <br />valuable to the study, but ently not available from existing datasets or <br />through cost effective spat I analysis. Tables and fields have been created to <br />store data values generate rom site visits, air photo interpretation or other <br />future analyses. <br />
