Descriptive name | Floodplains - Areas of revision not yet in the GIS floodplain layers. | |
File name | fp_lomxp | |
Spatial domain | Pima County | |
Abstract | fp_lomxp displays area boundaries in which the floodplain data has been revised by Letter Of Map Revision (LOMR), BUT THE UPDATED BOUNDARIES HAVE NOT YET BEEN INPUT INTO THE GIS FLOODPLAIN LAYERS, I.E. FP_DFIRM, FP_FLWAY, ETC. | |
Known errors/qualifications | The revision area boundaries were screen digitized using the FIRM panel as a reference. This layer may or may not have data in it at any given time. As LOMR documents are processed the relevant information is removed from this layer. A place holder polygon exits in the SW corner of the data in order to prevent the data set from registering as NULL when it is empty. This is necessary since an empty shapefile can't be converted to coverage format as required by the library. The place holder polygon is attributed as PLACEHOLDER in the CASENUM field. The MapGuide layer name for this layer varied: - Public maps: Floodplain not digitized - See paper documentation - Internal maps: LOMR Revisions - See LOMR document (PimaMaps appears to use this for both public and internal) | |
