Parcel Software – Prepare Land Acquisition DPR Quickly

Land Acquisition: In several projects, Land needs to be acquired (mostly by the Government bodies for developmental and infra projects like, Road, Railways, Canals etc...) or sometimes by private bodies for developmental purposes. To estimate the areas within a parcel or a complete parcel involves extraction of areas by creating the closed polygons for the area which has to be acquired. A typical example of the same is shown.

Parcel

These Acquisitions could be on one side of the road, or both sides. These conditions along with several other combinations have been perfectly blended in the module, to achieve seem less and accurate results.RTC data related to survey numbers can be imported in the software and the report of the software will be generated considering the percentage of land and related RTC details.


Benefit:

Saves considerable time in preparing the Detailed Project Report (DPR) for land acquisition software.

a. Introduction to Parcel Module of Civil Tools

Parcel Module of ESurvey Civil Tools gives solution for

  • Preparing an Area report of Land Acquisition or Utilisation of Survey Boundaries along the Project area

Using this module you can compute the area to acquire of various Survey Number as utilised in each pocket of the project area. To achieve the result, you need to follow these steps.

Preparation in Drawing File

  1. Each survey boundary to be defined by a closed polygon
  2. Each Village to be defined by a closed polygon with separate layer and give village name as the layer name
  3. Each Pocket/ROW to be defined by a closed polygon with separate layer and give pocket name as the layer name
  4. Each Non Compensatory boundary to be defined by a closed polygon with a separate layer name

Once this preparation is done, all boundaries with attached information to be exported to E Survey Civil Tools Interface

Working on ESurvey Civil Tools Interface

  1. Import boundary data Exported from drawing files (Both Survey Boundaries defining Village Map and Survey Numbers within Pockets)
  2. Import Survey boundary information from Excel as maintained in RTC

Once all this information is imported into Parcel module, then Parcel module can give report indicating how much area of a given survey number is occupied in a given packet

 

b. Preparing drawing to create parcel Boundary

Each Survey Boundary within the village boundary to be represented as a closed polygon. Similarly, each survey boundary within the pocket needs to be represented as a closed polygon. For each of these polygons, respective information to be attached. For Survey Boundary contributing to village map – You need to attach the Survey Number and Village name. For Survey boundary areas falling within a pocket, you have to attach the Survey Number, Village name and Pocket name.

There are multiple AutoLISP commands which will help you prepare this data. To start with, you need to have base map which has all survey boundaries defined. To make the program work, you need to AutoCAD entities in specific layers.

To create required layers for parcel module you have to use LSAY Command. This will display information about each layer which has to be created.

Parcel

Using a set of lisp command you have to prepare required data.

Parcel

Sl.

Command

Description

1

LSAY

Layer Specification for Parcels Module. This command will create all the layers with a Standard Layer name

2

HPLY

This is a quality check command. Hatch Polygons to Find Boundaries yet to be Created.

3

AVSB

Attach Village Survey Numbers to Polygons representing Survey Boundary  in Bulk

4

ATV

Attach Village Name to Village Boundary Survey Boundary

5

RDV

Read Information attached to village Survey Boundary

6

FEVS

After creating boundaries, attaching information might have been left out. Find Error in Village Survey Boundaries

7

EXSB

Export Survey Boundary, Village Survey Numbers (including attached information).

8

EXV

Export Village Boundary, Name of the village is taken from layer Name.

9

EXP

Export Chalk/DP boundary, Name of the Chalk/DP is taken from layer Name.

10

EXN

Export Non-Compensatory boundaries


c. Export boundaries to Civil Tools Interface from CAD

After preparing required boundaries and attaching  the required information to survey number boundary then, export CAD data to ESurvey Interface.

  1. Execute command EXSB to export Village Survey Number boundaries (including attached information)
  2. Run Command EXV to export Village Boundaries (each village boundary should be kept in separate layers with village name).
  3. Run Command EXP to export Pocket boundaries (You need to keep each boundary separate layer depending on type of pocket)
  4. Run Command EXN to export Non compensatory boundaries (Non compensatory Areas such as  Temple, Road, Nala Etc )

d. Import Boundary and Pahani information to Civil Tools Interface

Open ESurvey Civil Tools -> Go to File menu click on New File

Parcel

Select Parcel option and give Project Name click on the Save button

Parcel

Select Parcel submenu from Main menu

Parcel

Click on the Import button, Import window will appear, select boundaries option which boundary you want to import and click on Import.

Parcel

After importing data to interface drawing will create like below

Parcel

Import RTC information

Save RTC information in prescribed Excel template as shown below

Parcel

Click on the Import button, Import window will appear, select the RTC option and click on Import to import RTC details from Excel.

Parcel

After importing all the data, click on the process button in Parcels window to compute to get the results.

Parcel

e. Export Report and Drawing

Importing data from CAD which includes boundaries and related information and importing RTC data from Excel is key in Parcel project. Further, there is nothing much to be proceed, once you import the data and click on process button, all the reports will be ready.

Click on the Report button in parcels window and select Unit type required in report, click on the Export button to get Excel report files. (The software will export report in Metric Units or in Acre Gunta).

Parcel

Sample Report will appear as below

Exporting Drawing by clicking CAD button in parcel window.
