Base Map Data Model

• Inventory of USGS map features for multiple scales– 1:24,000, 1:63,360, 1:100,000, 1:250,000,

1:500,000• Cartographic Feature Type (CFT) approach

8

(Cartographic) Feature Types

• DLM vs DCM/ GIS & Mapping vs. only Mapping• Complex Domain

– Feature codes + attribute codes– Derived from VVTID approach

9

Cartography Table(s)

• Purpose: Assign cartographic rules for each representation based on feature types

• Uses: Look Up Table for:– Hydrating the data model– Setting symbol and label specifications

• Content– Feature codes + attribute codes– CFTID– Symbol and labeling specifications– Style specification– Alternate symbology and labeling– Query Strings for filtering and labeling (a.k.a. Generalization)

10

Hydrating the Data Model

• Feature Code and Attribute Code Combinations

• USGS DLG Data– Entity labels and attributes– Same codes for all scales

• VMAP Data– FACC codes

• Calculate CFT Tool

11

Symbolization, Labeling & Styles

• For specific map products• For multiple map products• For different scales of maps• Arc 9.0 capability

– Styles, layers, Label Manager, Maplex, Variable-Depth Masking, etc.

• Arc 9.1 Capability– Representation capabilities – representation

classes with representation rules, geometry filters, overrides

12

Supporting Elements of the Base Map Data Model

• Data• Geoprocessing Tools and Models

– Calculate CFT Tool, Hillshading, Append 9.0• Tables

– Carto LUT, Related Symbol LUTs• Layers• Styles

– USGS Topo, Recreation• Page templates

– Multiple scales, multiple purposes

Insights

• Develop data model based on requirements for specified output

• Digital Landscape Model (DLM) and Digital Cartographic Model (DCM)

16

Future Directions

• “What we want to do is to put the power back in the hands of the cartographers – allowing them the freedom to override the decisions that the computer made in order to provide absolute clarity. It’s about letting the cartographer put the art back into cartography where it’s needed.”– Representation feature classes and layers– Generalization– Symbolization

“Mineral or Hot – This code describes any well, spring, or water source that is labeled to indicate the water is hot or contains minerals. Includes mineral, not, sulpher, alkali.”
