Data Driven Pages in ArcGIS

When we need to create large scale maps such as 1:1000, 1:5000 etc... it is not possible always to export entire map into a single A4 or A3 size page. Therefore we can use Data Driven Page option in the ArcGIS which include Grid Map Index as a key to the Map.

Step 1,

Right Click on the ArcGIS Tool Bars area - Add Data Driven Pages Tool bar to your ArcGIS Desktop.



Step 2,

Add data you prefer for this project and make sure to change the scale in to large scale such as 1:5000 1:2000 etc... The change your view to 'Layout View', You can see your entire map in not visible withing the map area.


Step 3,

Go to Arc ToolBox - Cartography Tools - Data Driven Pages - Grid Index Features


Step 4,

Assign output feature class and select Input features as you need, you can add any amount of data layers. Then Tick both check boxes (Generate polygon Grid that intersects input feature layers or datasets and Use page unit and Scale). Then Map scale will automatically assign the layers map scale (Here I have used 1:5000 for layers hence Grid Index Features also automatically assigned 1:5000 scale). Then assign the size of your map sheet need. Here I have assign 20 cm for both Polygon Width and Height. Use drop down box to assign the unit you need, (Make sure for your layers also you have use the same unit such as km, m or cm etc...)Then assign number of Rows and Columns you required for your gird. Keep other optional features as it is. then Press 'OK'


Step 5,

Now your map Index has been created, 



Step 6,

This is the attribute table of the created Map Index, you can see it has given Page Name and the Page number for each Grid. 



Step 7,

Now we have to use Data Driven Pages Tool bar to assign our created Map Index to our data layers.
Click on Set Up data Driven Pages then in the Index layer "layer" select created Map Index, for the Name field select "Page name" of the Map index attribute.  and assign Page Number for the Sort field.



Step 8,

In the "Set Up Data Driven Pages" select Extent Tab, and then assign 100% as the Best Fit. Press "OK"



Step 9,

Now if you click on the Next page option you map shift to the next page, 


Step 10,

Now we have to show the map page in the Grid Index, for that add new data frame, 


Step 11, 

Add your map index to the new data frame.



Add Extended Indicator for new layer, 



Step 12,

Now you can see its indicate what page of the map on the Map Index, now we can add Data Driven Page Name to the Map to improve the readability of the map. 


Step 13,

Now we have to export Data Driven Pages to  PDF, for that simply go to Files- Export map  then select PDF, once you select PDF you have to tick on the All pages option the "Options". 


Once you exported to PDF you can see your map how it reefers to the Map Index.
