JADOCS map backgrounds use NGA standard map products that fall into which two categories?

• A. Raster and Vector
• B. Digital and Analog
• C. Vector and Rasterized
• D. Photographic and Topographic

Answer: (A)

Map data used as backgrounds in JADOCS come in two formats: raster and vector. Raster is image-based data made up of pixels, such as satellite imagery, orthophotos, or scanned topographic maps. It provides a continuous picture of the landscape but isn’t easily measured or edited feature-by-feature. Vector data, on the other hand, represents features as coordinates—points, lines, and polygons with attributes—allowing precise queries and editing of roads, boundaries, hydrography, and other map features. NGA standard map products are organized into these two categories, which is why they’re used as backgrounds in JADOCS: you can display a detailed image backdrop (raster) or a scalable set of feature data (vector) depending on the task. The other options don’t reflect how NGA categorizes its map products—digital vs analog implies a legacy medium, and “photographic and topographic” isn’t the formal two-format division—so raster and vector is the correct pairing.
