Layer Name: Ground Water Wells
Coverage Name: WELLS Layer Type: Point Geog. Extent: Main Hawaiian Islands Projection: Universal Trans Mercator, Zone 4 Description: Ground Water Index Wells database for main hawaiian islands. Source: Department of Land & Natural Resources, Division of Water Resource Management wells database (maintained in DBase) March, 1997. History: DLNR, DWRM generated points in Arc/Info using coordinates stored in DBase files maintained and continuously updated by DWRM. Database is periodically converted into Arc/Info. Last converted to Arc/Info in March, 1997. Attributes: Points: AREA not used - point data PERIMETER not used - point data WELLS# Point internal number (for Arc/Info use) WELLS-ID Point ID (for Arc/Info use) ISLAND Island WELL_NO Well Number - 6 digits, assigned by DWRM, based on latitude/longitude position of well.
