LAC 43:XXVII.1901. General Requirements

A. The following requirements establish uniform criteria and guidelines for the development of map feature elements to be included on all planimetric, topographic and/or parcel maps to be prepared under these standards. B. All map feature elements are grouped into eight general layer categories as discussed in Chapter 13 and hereinafter defined as follows. Layer Category | Category Description 1 | Margin and Grid 2 | Transportation 3 | Hydrology 4 | Terrain 5 | Structure 6 | Utility 7 | Topographic 8 | Parcel 1. A tabulation of all feature elements contained within each category together with associated feature code numbers, graphic representations, element types, and graphics and text requirements are set forth within accompanying §§1917-1931, Appendices B-I, inclusive. C. All feature elements should be accurately digitized to scale whenever possible rather than symbolized in order to facilitate subsequent GIS applications. Whenever symbolization is necessary, the actual size of the symbol should be no larger than required to provide satisfactory visual interpretation at the final map manuscript scale. Relatively small feature elements which can not be satisfactorily photo-interpreted on reduced scale map imagery should not be plotted.
