(1) Vendor needs to provide GIS base map updates service to the government authority located in Mobile, AL.
- All digitized features must be both visual and coordinate edge matched with features from existing data, in adjacent tiles, sheet edges and at model breaks or other artificial boundaries within a tile. No edge match tolerance will be allowed. Attributes for adjoining features must also be identical.
- All vector features that share a common boundary, regardless of digital map layer, must have the exact same digital representation of that feature in all common layers.
- No duplication of points will occur within a data string.
- high quality cartographic appearance will be achieved. Transitions from straight line to curvilinear line segments will be smooth and without angular inflections at the point of intersection. The digital representation must not contain extraneous data at a non-visible level. There will be no jags or hooks or zero length segments. Curvilinear graphic features should be smooth with a minimum number of points. When appropriate, line smoothing programs should be used to minimize the angular inflection in curvilinear lines. Any lines that are straight or should be straight, should be digitized using only two points that represent the beginning and ending points of the line.
- The digital representation of linear elements must reflect the visual network structure of the data type.
(2) All question must be submitted no later than April 12, 2023.
