- 12. 3DS.COM/GEOVIA© Dassault Systèmes | Confidential Information | 2/16/2024 | ref.: 3DS_Document_2012 12 12 Surpac String Concept The most common file format used for storing information in Surpac, is a String file. A string file contains coordinate information for one or more points, as well as optional descriptive information for each point.
- 13. 3DS.COM/GEOVIA© Dassault Systèmes | Confidential Information | 2/16/2024 | ref.: 3DS_Document_2012 13 13 String Hierarchy Data in a string file is classified into: Points Segments String All points in a string file are grouped into segments, which are further grouped into strings.
- 14. 3DS.COM/GEOVIA© Dassault Systèmes | Confidential Information | 2/16/2024 | ref.: 3DS_Document_2012 14 14 String Hierarchy The example shows conceptually how a string file contains string, which contain segments, which contain points.
- 15. 3DS.COM/GEOVIA© Dassault Systèmes | Confidential Information | 2/16/2024 | ref.: 3DS_Document_2012 15 15 String Classification Open String – a straight or curved line. If more than one open string exists with the same number, then these are called open segments of the same string. Closed String (as per string directions) Clockwise (area of inclusion) Anti-clockwise (area of exclusion) Spot Height – a series of random points linked together by a string number, but outlining no particular feature.

The comma ( , ) is used for a range that includes a start, an end, and, optionally, an increment. <start>,<end>,<increment> Note: When the increment is 1, use <start>,<end> without specifying the increment. The semicolon ( ; ) is used to identify unique values, or to separate multiple ranges.

The corridor width is equal to the towards distance plus the away distance. When a plane is active, data within the corridor is displayed, and data outside the corridor is hidden. Geologists use planes to view vertical cross-sections of drillhole and surface topography data. Engineers use planes to view horizontal sections of a block model while creating a pit design. Surveyors use planes to create cross-sections of areas which have been mined to display the cut for a specified period.

To create a DTM a relative string file is must. Even to view a DTM in Surpac window its string file must exist. Any editing in the string file after making DTM results loosing the DTM. The DTM is to be created again.

File Based Method • string files need not to be displayed on the screen, DTM is formed and saved into a file automatically, it has the opportunity to declare Spot Heights, Break Lines.
