Draft operational guidelines of digital india land records modernization programme (dilrmp) introduction

9.2.3 At area layer
Some of the alamats (in-situ) that are to be represented by areas must be provided in an area layer. The area layer required for this purpose must contain the attribute field “shade” along with other necessary fields. The following table contains the “shade” column for the above mentioned area layer. The other columns are given as descriptions to the “shade” column. The column named “Sl. No.” is the serial number of the various symbols as per the conventions followed by the Directorate of Land Records and Survey. The base name of the files for the area layer for the alamats must be “alma” i.e. the “. shp” file for the line layer must be “alma.shp”. The names of other necessary files (.shx, etc.) for the same line layer must be given accordingly.
Note: i) Some alamat notation comprises of a line and several points on the line. In such cases the lines are to be provided in the line layer and the points are to be provided in the point layer that is described in Table 1.
ii) Attribute Naming: The “shade” attribute column must be a character field having a maximum length of 4 characters.

Table 3

Item	Shade (specified by the NIC)	Description	Required features for West Bengal (NR: Not Required, R: Required)
Pucca buildings (in situ)	1	Specific to State	NR
Pan baroz	2	Specific to State	NR
Sand char	3	Specific to State	R (.dbf)

Note: IMPORTANT

1. The “.shp”, “.shx” and the “.dbf” files for the mouza containing the area and the line layer should be named as “.shp”, “JL.shx” and “JL.dbf” respectively. Thus, if the JL No. of a mouza is 100, then the three abovementioned files should be “100.shp”, “100.shx” and “100.dbf” respectively. The files are to be placed in the “JL No.” subdirectory under the corresponding “PS Code” directory in the following format:

\ \ .shp

\ \ .shx

\ \ .dbf
Thus, if for a particular mouza, the PS Code is 50 and the JL No. is 100, then the files corresponding to the layers of that mouza should be organized as follows:
50 \ 100 \ 100.shp
50 \ 100 \ 100.shx
50 \ 100 \ 100.dbf
2. If the mouza map comprises of more than 1 sheet, then the files for all the sheets are to be given the same names and as per the convention mentioned in point 1 above. However, in order to avoid controversy, the files must be kept in different subdirectories denoting the sheet number under the “JL No” directory, which itself is kept under the “PS Code” directory. Thus, if the mouza map with JL No. 100 (see the example in point 1) comprises of 2 sheets then the file should be organized as follows:

For sheet no. 1 For sheet no. 2

50 \ 100 \ 1 \ 100.shp 50 \ 100 \ 2 \ 100.shp

50 \ 100 \ 1 \ 100.shx 50 \ 100 \ 2 \ 100.shx
50 \ 100 \ 1 \ 100.dbf 50 \ 100 \ 2 \ 100.dbf
3. The layers for the images and the alamats need not be qualified with their corresponding JL Nos., but they must be kept in the same directory along with the layer files mentioned in the above two points. The files will be named as centroid.shp, almp.shp, alml.shp, scale.shp, bnd.shp, mbnd.shp, img.shp, alm_bata.dbf, first_last.dbf, missp.dbf, name.gif, lege.gif, bata.gif, sign.gif, etc.
4. The attribute field giving the plot number of each plot of the mouza is a compulsory field. It must be a 5-character field and have the name “plotno”.
5. The list of conventional symbols for the alamats as followed by the department should be referred whenever required.
6. For symbols, which are not “in-situ”, the points of insertion of the symbol are to be given at the approximate center of the symbol in the point layer for alamats.
7. The scale for each map should be digitized and provided as a separate line layer along with the other layers for the mouza. The base name of the files for the line layer for the alamats must be “scale”, i.e., the “.shp” file for the line layer must be “scale.shp”. The names of other necessary files (.shx, etc.) for the same line layer must be given accordingly.
8. The values in the different attribute fields in the various layers should be left justified.
