- About this tutorial
-
- This tutorial is intended to give a quick understanding of how to use both
- components of Topographer. It refers to several of the example maps supplied on
- the release disc, and should be worked through from start to finish if it is to be of
- maximum benefit.
-
- Part 1 - Constructing a new map
-
- Load the Start map from the Tutorial directory into Topo2D in the normal
- way. The idea here is to add to the Start map to form the Later map, which
- is also present on the disc for reference.
-
- Choose the Show coords option to bring up the coordinates window. This will
- help you to position the pointer correctly. You will find it easier to position
- features accurately if you set the mouse speed to Slow using the !Configure
- application supplied with your computer.
-
- The numbers in the grid coordinates window change as you move the pointer on
- the map. You should see five digits in the Coordinates window, if not check that
- you have the five digits option selected in the Map=>Grid window. In the
- following instructions, positions on the map are referred to by a ten figure
- coordinate. This ten figure number is made up from 5 figures for the Easting
- position and 5 figures for the Northing position eg 00298 00459 means 00298
- Easting and 00459 Northing. The first three numbers relate to the grid position as
- shown on the map eg 00298 Easting means grid 002 on the horizontal axis and 98
- divisions within the grid. From this you can see that Topographer allows you to
- position things with great accuracy to within one metre.
-
- Hint: To move about the map quickly, drag either scroll bar with Adjust in any
- direction to scroll the document in both horizontal and vertical directions.
-
- Note: When following this tutorial read each paragraph first before starting
- to place the feature.
-
- Choose the Show features option on the document menu to bring up the features
- window. Choose the Bridge feature and draw the bridge from 00208 00450 to
- 00602 00207 by first clicking Select at 00208 00450 and then double-clicking
- at 00602 00207.
-
- Note: When drawing line features you can backtrack by clicking Adjust to erase
- one point at a time.
-
- Choose the Road wider than 4m feature (yellow) and start the road by
- clicking Select at 00000 00690 move to 00208 00450 and click Select while
- holding down Shift. Holding down Shift will ensure that the road goes over
- the bridge! You need to do this at both ends, so move the pointer to 00602
- 00207 and click Select while holding down Shift again. Complete the road by
- clicking select at 00750 00090 and double-clicking Select at 00999 00140.
-
- Now choose the Secondary road feature (orange) and start the road at 00602
- 00999 and move to 00660 00690. We need to join these two roads neatly so
- this time finish the road by holding down Ctrl and clicking Select once. A
- neat junction should be formed.
-
- Choose the Church with tower feature and place the church at 00636 00685 by
- clicking Select.
-
- Place a pub at 00664 00722.
-
-
- Place a post office at 00634 00634.
-
-
- Scatter a few buildings around the road junction.
-
-
- Choose the (blue) river symbol and edit the field at the bottom of the
- Features window to make the river 2 metres wide and then click on OK. The
- river starts at 00740 00320 and runs through 00695 00350, 00675 00390,
- 00670 00470, 00650 00550, and 00973 00999.
-
- Place a caravan park at 00700 00585 and a camp site at 00725 00600.
-
- Draw a railway from 00000 00975 to 00700 00920 and to 00840 00999.
-
- Place a station at 00565 00930.
-
- Finally, place a level crossing at 00625 00920.
-
-
- If you were working with the full version you would now do the following:
- =========================================================================
-
- Save the map in the normal way, and export it to Topo3D.
-
- Once in Topo3D, you can choose from three pre defined viewing positions or
- create your own. The first position giving a view of the village is already set up.
-
- Click on Make view to see your creation.
-
- To choose another viewing position use the menu item View library=>Recall=>
- and select from Village, Station and Bridge by clicking on the required one. You
- can then use Make view again to create your scene.
-
- The map called Later in the Tutorial directory is a finished copy of the map you
- have just created - so you can compare your map with how it should look.
-
- You may like to experiment with the other maps supplied on the disc to gain
- experience at using the various functions.
