The OS background is too prominent in its default setting. I want to make it grey scale and reduce its intensity. This can be done using the style override: In the Adjust Image Styles box, I have selected Grey Scale and select grey scale and moved the translucency slider to 50% Next I am going to add some flood data from the Environment Agency. Again, I have used the Open table button to open this. This is a Vector Layer comprised of lines and polygons. MapInfo allows a vector layer to be comprised of a mixture of points, lines and polygons, unlike ArcMap. However I don’t like the default styles. Right click on the layer in the Layer Panel to open the Layer Properties. Notice the different options for a Vector Layer compared to the earlier options for the OS data:- I have chosen a dot fill for the flood zone polygons, as I want to be able to see the background map through them. The background pull down gives the option of a background fill colour. It is important to leave this unticked if you want to underlying layers. Min/Max Scales.You may have noticed this feature in the style override controls. These set the min/max scales that a layer is displayed at. Note the scales are related to the Zoom (Window Width) NOT the map scale! To find out the window width at a particular scale, adjust the map scale and note the Zoom (Window Width) value. The flood data is over-riding the borough boundary which I think looks a little untidy. Fortunately, it is possible to re-arrange the drawing order by moving layers up or down in the layer panel. It is also possible to group layers, which is useful on drawings which have a lot of layers. Finally I would like to add some points to show the main settlements within Wokingham. Labels are preferable to entering text: As you can see above, Sonning is over writing the label for the settlement to its north east. If a label needs to be adjusted manually, double click it to open the Label Style dialogue box: The anchor point, offset and label line can be adjusted to clarify the labels. It is also possible to manually enter text and change the layer font. Note that manually adjusted labels may not refresh when adjustments are made using the layer’s properties box. Ensure the table has been packed before applying labels. MapInfo assigns labels to a specific row in the table. For example Twyford is in row 5. If rows 2,3,4 were deleted, Twyford would now be in row 2, but MapInfo would still assign the label to which ever point is in row 5. If Finchampsted has moved up to row 5, the label Twyford would now have a long line pointing south to Finchampstead…..in other words it will be a total mess! The only solution is to delete all the labels and start again. Raster data is pixel based, so there is a limited range within which it can be scaled while still looking acceptable. As a rough guide, I use the following OS products at the following scale ranges Clutter is another factor in deciding what scale to use background maps at. Mastermap becomes too cluttered at smaller scales. Vectormap is a new OS product designed for background mapping. It is available in both local and district, as well as raster and vector. Its flexibility and clean, uncluttered styles enable it to be used across a much greater range of scales. Distance Units, I change these to centimetres when I want to set the map to a specific scale. This allows me to easily enter the map scale as MapInfo always gives the scale relative to 1cm on the map. (e.g. it is easier to enter 1cm : 50,000cm than 1cm : 0.5km). It is easy to change back to metres or kilometres when taking measurements. Display Grid Reference: I may change this to Decimal Degrees to easily see the British National Grid co-ordinates Distance/Area Using. I set this to Cartesian when using British National Grid (or other Cartesian system) and Spherical when using a spherical co-ordinate system (e.g. WGS84). Display In Scroll bar: This option can be set more quickly by simply clicking the display information in the left of the scroll/status bar. this is a great inspiring article. i am pretty much pleased with your good work. you put really very helpful information. keep it up. keep blogging. looking to reading your next post. lista de email lista de email lista de email lista de email lista de email Source.
