GISP General questions with correct answers

Scanning a map document to JPG format Correct Answer-An example of analog-to-digital conversion Curve, point, surface Correct Answer-Components of the OGC geometry object model Topology Correct Answer-Most effective method for maintaining data quality to ensure that no line features of a stream center line layer intersect the polygon feature of a land cover layer 90% Correct Answer-According to National Map Accuracy Standards, what percentage of features must be within 1/30 of an inch or less from their intended horizontal accuracy on maps with scales of 1:20,000 or larger? Quad trees Correct Answer-A compression technique for raster data that subdivides data into quarters and data structures based on the successive reduction of homogeneous cells. Reduces raster storage requirements. It also is dependent on the complexity of the feature and the resolution of the smallest grid cell. Run Length Encoding Correct Answer-A compression algorithm for raster data that represents an image in terms of the length of runs of identical pixels. A very simple form of lossless data compression in which runs of data (that is, sequences in which the same data value occurs in many consecutive data elements) are stored as a single data value and count, rather than as the original run. Euclidean distance Correct Answer-The straight-line distance, or shortest possible path, between two points
