These models are collected around ten areas of relevance for both fields, forming separate chapters: Sounding, Spot Elevation, Isobath/Contour, Hachure/Hatch, Shaded Relief, Land Classification, Figure-Ground, Stratigraphic Column, Cross Section, Line Symbol and Conventional Sign.
For accuracy assessment of the ASTER and SRTM ASTER DEMs, spot elevation were extracted from the toposheet as a reference data.
The authors cover the following modes through comparing and contrasting them: sounding, spot elevation, isobath, contour, hachure, hatch, shaded relief, land classification, figure-ground, stratigraphic column, cross section, line symbol, and conventional sign over the course of the bookAEs ten chapters.
Thus, a Digital Terrain Model (DTM), vector contour data, and vector spot elevation data were delivered and evaluated.
The surveyor must also include the information that was used to locate the spot elevation in the field book.
Another form of identifying elevations is to mark proposed heights of objects by labeling the object with a spot elevation.
The "rule-of-thumb" for vertical accuracy expressed as ratio of flying height is that spot elevation accuracy should fall within the range of 1:8000 to 1:15000.
The top of the ground floor floor should have a spot elevation of OKFFB = 159.
The top of the ground floor is a floor spot elevation of OKFFB = 159.
The top of the floor-floor should have a spot elevation of OKFFB = 159.
1988, grid coordinate system, nclude the following in the title block: title of survey, location, north arrow, certification and date and all revision dates, one (1) foot contour interval and spot elevations, provide elevations at all tops and bottoms of banks and all tops and bottoms of slopes, tie elevations into nearest national geodetic survey benchmark.
