A Strip Plan typically indicates the location, lengths, quality, etc. in a graphical manner. Preparation of strip plans is a very common practice to get the feel of the project details at a glance. Strip plans are prepared for a variety of projects like, roads, railways, canals, etc. These are also prepared at various stages like desk study (includes feasibility and DPR) and execution stages.

Considering a typical road project, the stages of preparation of the strip plan are described here.

1. Initially, the details of the Road are collected and commonly referred to as Road Inventory Survey. Here all the details like the road condition, road width, drain details, village limits, road appurtenances, religious structures, monuments, cross drainage structures, bridges, etc. are indicated.

A Typical Inventory chart is shown below.

2. The Road center-line is assumed to be straight and plotted according to the length of the project.

3. All the collected details are generally classified as linear features which include, roads, bridges, village limits, drains, etc. and point features which include electric poles, culverts, telephone poles, bore wells, etc.

4. All the linear features are plotted with reference to the center line on either side. All the point features are drawn judiciously to indicate these at the most possible correct location.

5. Sometimes even the details are tabulated below the drawing to indicate features and locations.

 

A Typical Strip Plan is shown below.

Preparing these drawings could be hectic as one has to spend a lot of time to include all the details by manually placing the details in line with the inventory.

Strip Plan Module can ease the drafting procedure considerably, by importing the data from the excel template and plotting the same in the CAD package. This will save time considerably and, also, no data is missed during plotting.

ESurvey CADD offers interpolation in 3 different ways

a) Straight Line Method: Weighted Average Method / Straight Line Method where with reference to any 2 selected texts interpolation can be done. Distances are measured from the interpolation point to reference both the text and reference values are given weight depending on the distance and interpolated value is derived.

b) TIN Method: Using available points, a surface using the TIN method is created (Triangulated Irregular Network). Each triangle is created in 3D and interpolation values are derived. Considering this is the most widely used interpolation technique.

c) 3D Line: 3D lines are created connecting reference code points. Value is interpolated depending on the particular 3D line segment. This type of interpolation gives better results when undulated surfaces like Irrigation Canal are surveyed.
An easy way to interpolate points at any intervals using the actual surveyed data for generating Cross Sections along the longitudinal section.
"Interpolate" allows obtaining values at regular intervals. It interpolates elevations at each cross-section along the longitudinal section, which may further be exported to excel for section generation. Practically, surveying at regular intervals is not possible for various reasons. Thus, to obtain values at regular intervals, points are interpolated. This interpolation is often done manually with a lot of calculations. To address this issue, Interpolation has been developed. It interpolates elevations at each cross-section along the longitudinal section, which may further be exported to excel for section generation. It also uses the three most commonly used and proven methods of Interpolation techniques for data processing - Straight line, TIN or 3D interpolation.
Key Features:

  • Interpolation along an alignment using any of the three methods – Straight line, TIN or 3D interpolation
  • Create 3D polylines by selecting elevation texts
  • Exports interpolated cross-section and longitudinal section values to excel or section generation software

Benefits:
  • Interpolate values quickly at required points on a surface without getting into complex surface building techniques

ntroduction to Traverse Correction

A Traverse consists of series of related points or stations, which when connected by angular and linear values form a framework.

The Purpose of a traverse surveys is to control subsequent detail, i.e. Fixing of specific points to which details can be relates. The accuracy of the control survey must be superior to that of the subsidiary survey.

 

Closed Traverse:

When a series of connected lines form a closed circuit, i.e. When the finishing point coincides with the starting point, then it is called as a closed traverse. These closed traverse surveys have many applications like fixing the boundaries of ponds, forests etc.

 

Open traverse:

When a sequence of connected lines extends along a general direction and does not return to the starting point, it is known as ‘open traverse’ or ‘unclosed traverse’.

 

Traverse Correction Procedure

Present techniques used in traversing using total station as an open traverse. The steps are as described below.

GPS pair points are fixed at a convenient distance, approximately about 3 to 5km. Care has to be taken that the pair of GPS points is fixed at a reliable distance (at least 60m is advised for better results) and on good monuments. These points are fixed in such a way that they are clearly inter visible and should cater for placing the total station firmly on the GPS stations,

Total station is to be checked for its calibration, prism constants for the prisms to be set in the instrument to avoid errors.

Total station is then used to conduct the traverse between the GPS points. This type of traverse ensures that the survey is started from a known pair of points and is closed on known pair of points. Care has to be taken that the last bearing is also taken for correcting the Adjustment.

There are several methods to correct the traverse adjustments. However, in most of the cases Bowditch rule is considered to bethe most reliable. The other methods like transit method, Crandall method, Least Square Methods are used very rarely. The most accurate method which is known as a adjustment correction by the least square method is used when the accuracy required is very high. This method finds itself applicable in the projects like tunnel works and works warranting for a higher the accuracy.

 

Traverse CorrectionModule in ESurvey CADD Software

“Traverse Correction” Module of ESurvey CADD is both excel based and CAD-based solution to fix the closing error encountered while plotting survey data error by distributing the error among the points by adopting a process called Traverse Correction, and generates detailed calculations. In this module, based on the input data, the traverse correction can be done by Bowditch, Transit or Crandall’s Least Square Methods. To know more about the software for Traverse Corrections, Please click the links below.

  • Traverse Correction – Open Traverse
  • Traverse Correction – Closed Traverse
  • Traverse Correction – In CAD Package

Bowditch Method of Traverse Adjustment

This method is widely used for Closed and open traverses. Open Traverses means that the starting and closing station is fixed with known Co-ordinates. Fixing up of known co-ordinates is generally done by using DGPS.

A Traverse is run between these two fixed points and then for errors Adjustments are done.

To understand the method of adjustment, it is required to know the concept of vector geometry. The Departures and Latitudes between 2 points are established. These calculations are done for each leg of the traverse until the Last station, and are tabulated.
