Software for Preparing Tippan Map Using Ladder Data - Ladder to Map

Area Calculation for Excavation, Under Cut, Over Profile

Tippan

  Ladder to Map

Lisp Package for developing the ladder diagram and creating the Boundary with options to automatically dimension the entities, find the areas.

Tippan is a basic survey document prepared in the field while doing a survey. It is a document which contains field measurements parcel wise (For each survey boundary). Most of the maps available are hand-drawn and not to scale. This Module is a very simple and helps you to create the Tippan maps to scale in very simple steps. It’s a collection of lisp Routines which simplifies every step in creating a Tippan boundary by eliminating the efforts of converting measurement unit, drawing perpendiculars and changing dimensions.

Converting the Land records into digital format is now largely adopted all over, and these tools are very convenient to achieve the same.

Features:

  1. Create ladders by reading the data directly from the field book by eliminating the process of typing them into text format and then converting them as drawings or type each and every component in cad packages.
  2. Draw perpendiculars easily
  3. Adjust ladder lengths easily
  4. Create Boundary automatically referring to Ladder Diagram
  5. Create dimensions of ladder entities, boundaries along with area in a single command
  6. Get the dimensions in metric system as well as Acres and Gunthas which is also widely practiced

Benefits:

  1. Save considerable Time in drawing Tippan Diagrams

  1. LTMT Command: Link to meter Conversion

This function is simple conversion tool to convert number of links to Meters.

Menu: Link to meter Conversion (LTMT)

Functionality: Converting links to Meters measurement

Procedure:

  • Type LTMT at the command prompt.

  • Type Number of Links : <20>

Result:

20.000 Links = 4.000 Meters


  1. CTMT Command: Chain to Meter Conversion

This command is a conversion tool for converting given Chain and Anna to respective distance in Meters

Menu: Chain to Meter Conversion (CTMT)

Functionality: Converting Chain to Meters measurement.

Procedure:

  • Type LTMT at the command prompt.
  • Type Number of Chains: <10>
  • Type Number of Anna : <5>

Result:

10 Chains and 5.000 Annas = 103.73 Meters


  1. CTL : Create Layer for Tippan Application

In tippan software there is a Specific way you have to name the layer to help the program to identify the entites. For example you have to put all the working lines of first tippan map in layer “TP_01”.

Creates layers for tippan application. Go to ESurvey Civil ToolsàCreate layers for Tippan Application (CTL)

Menu: Create Layer for Tippan Application (CTL)

Functionality: Creating layers which required for Tippan Application

Procedure:
Type CTL at the command prompt.

Result:

10 Layers Created for Tippan Preparation: It will create layers TP_01 to TP_10 layer.


  1. DPER: Draw Perpendicular line with reference to Base Line

Tippan map is typically made of a base line and perpendiculars drawn to base line. DPer command draws perpendicular lines to base line.

  • Go to ESurvey Civil Tools àDraw Perpendicular to Base Line(DPER)

Example: Line for which perpendicular lines are required.

Select the base line: (Select the line)

Pick a point for Drawing Perpendicular:

Pick a point for Drawing Perpendicular: (pick point from where line should start)

Repeat..


Example:


  1. BPL: Break Base Line

Tippan program expects you to draw draft base line and perpendicular lines. Once that is done, to make the map final, you can prepare drawing to scale with further commands. First base line has to be converted into pline with multiple vertex, that can be done using BPL command after drawing the required perpendicular lines.

Go to ESurvey Civil Tools Tippana Break Base Line (BBL)



  1. LPM: Locate Point at Given Distance in Meters

When preparing map to scale, you may require locating some points using LPM command you can draw line of given length at particular distance.

LPM


Select the First Point: end of

Type the Distance: 3



  1. CSM: Change Segment Length of Base Line in Meters


Command: CSM

Select Polyline for Changing Segment Length:

Type the New Segment Length: 4 meter

Result: After updating Distance Once again


  1. LTM: Lengthen Side Line of Tippan in Meters


Command: LTM

Select Tippan Perpendicular line to Lengthen:

Type the New Length: 16 meter



  1. ELM: Export Ladder in Meters

Command: ELM
