EXTRACT LONG AND CROSS SECTIONS ALONG ANY ALIGNMENT
This function is used to extract long sections from ground or design data along a pre-defined route. Cross Sections and long sections may be extracted from either lines or points.
SURVEY CALCULATIONS, ERROR FIGURES AND CONTROL SURVEYS
The functions in the Survey Module permit you to gather, compute and edit data from a variety of sources. The Terrain Module functions create a mathematical model of one or more surfaces and permit information such as contours, volumes and sections to be derived from it. Data can be manipulated from the basic collection stages all the way through to final contract drawings.
The Error figures features adjust a provisionally fixed point that has redundant observations by means of a least squares solution, or a graphical fix of the error figure, or both. A rough fix for the point should be calculated prior to using this routine and usually this will be done under Survey Calculations. The data for the calculation must be provided in the form of a field book.
Control Surveys allow you to perform a least-squares adjustment of a network of 2D points and associated distance and direction observations. You are also given the resultant error statistics.
POWERFUL SURVEY REDUCTION ROUTINES
Tache Reduction: Tache data can be typed directly into the spreadsheet. Each line of the spreadsheet represents a set-up station, an outward orienting ray or a tache observation. Tache observations can either be an EDM or prism observation, a tache or staff observation or a polar observation (generally from a total station).
Flat Traverse : This function reduces a conventional simple traverse, in which it is assumed that all distance reductions have been carried out separately and that the distances supplied have been reduced to the horizontal. It therefore does not require the entry of the vertical angles unless a height traverse has been incorporated. It can also be used for theoretical calculations, such as cadastral reconstruction, where an adjustment is required.
Full Traverse: This routine is used to reduce a traverse where the distances provided must be reduced to the horizontal and also require correction for Sea Level, Scale and Temperature. Vertical angles must therefore be supplied in the field book and the average elevation of the traverse and the temperature correction will have to be supplied.
Slope Traverse: A slope traverse, using slope distances, can be reduced by incorporating vertical angles.
Spirit Level Reductions : These routines permit the reduction of normal and cross-section spirit levels by the rise and fall method. The data for spirit level reductions must be provided in the form of an ASCII field book file.
HELMERT AND GEO-TOPO TRANSFORMATIONS
If more than two points have known coordinates on both systems there is redundancy and a least square (Helmert) system can be used to obtain the final parameters.
Geo-Topo transformation can be used to convert geographical coordinates in the form of degrees, minutes and seconds of latitude and longitude, to Y and X coordinates in the project projection in Civil Designer format. An ASCII file is read and another one is written. The converted coordinates can be set relative to any standard line of longitude.
SUPPORTS ASCII, BOOKER, LOGGER, WILD, GEODOS, CEASER AND SOKKIA
We support many different data formats (field books) which can be imported into Civil Designer. Terrain point coordinates may also be exported to total stations or to WILD equipment.
FULLY COMPATIBLE WITH DWG AND OTHER FORMATS
Knowledge Base is a founder member of the Open Design Alliance and, as such, our inside knowledge of the DWG drawing structure ensures high compatibility when loading and saving DWG and DXF drawing formats, including Paper Spaces. In addition we also support loading of Caddie CEX, Arcview SHP, Microstation DGN and Ultimate CAD UCX files. This gives you unprecedented flexibility to move between drawings without having to worry about incompatibilities and data exchange problems.
