  • 1.  Hotspotting in Map Info Pro v17

    Posted 08-23-2021 05:47
    Good Morning,
    I am new to Map Info Pro v17 and an absolute Technodinosaur. Reading the manual is far to technical and when I have searched for youtube videos, they go so fast.

    What I have to do is plot some Latitude and Longitude grids onto a map, to show me where my hotspots are. Can someone explain in simple terms. how to do this?

    Your time and help in this is greatly appreciated.

    Kind Regards
    Rosemary

    Hi Rosemary

    Thanks for reaching out.
    Can you explain a bit more about the data you currently have that you want to show in MapInfo Pro?
    Is it CSV or Excel files holding lat/long values along side other values?

    Hi again,

    Let me give you some ideas.

    Opening a Basemap
    Let us start by opening a base map to give your data some context. From the Open control on the Home tab, select one of the base maps. 

    I will open the Hybrid base map which will open Bing Hybrid with aerial imagery overlayed with streets and area names.

    I'll use the Zoom In tool to zoom to my area of interest. You can also wait, and use the extent of the data file you are loading in the next step to control the extent of the map.

    Loading the Data File

    The next step is to open your file into MapInfo Pro. From the Home tab, click on the Open Table control.

    In the Open dialog change the file type to Microsoft Excel (*.xls, *.xlsx) from the Files of Type list. Now browse to the folder where your data file exists and select it.

    If you need to edit your data in MapInfo, or if you have a large dataset, it's recommended to save the data file into a native tab format. To do so, check the option Create copy in MapInfo format for read/write. This will automatically create a copy of the data in a native tab file in the same folder as your data file, and open this copy.

    As I chose to open a Microsoft Excel file, I will be presented with a few configuration options.

    In the dialog Excel Information, I will have to select the Named Rage to open. This will typical refer to a specific sheet in your Microsoft Excel file. Below you can see I have selected InputData as my sheet.

    As I know that the first column in my sheet holds columns names, I check the option Use Row Above Selected Range for Column Titles.

    In the dialog Set Field Properties, I can rename the columns and change the Column Types. One thing to pay attention to is that Integer columns typically are seen as Float columns. You can in this dialog force MapInfo Pro to load the columns as Integers as you can see I have set for the column HouseNo. You will of course need to know your data as some Float columns do hold floating values, such as coordinates or lat/long values.

    Hit OK to load your data into MapInfo Pro.

    At this stage, MapInfo Pro doesn't yet recognize any spatial information in your data. Therefore the data is shown in a browser window.

    Mapping the Data

    Now you have to tell MapInfo Pro how your data can be mapped. In our example, you have coordinate values in two columns. You can use these to create points for your data.

    From the Spatial tab, select Create Points from the Create control in the Create group. If you have problems locating some of the features, you can use the Quick Search control to locate them.

    In the dialog Create Points, select your data file as input. Then make sure that the coordinate system matches the coordinate system of your coordinate values.

    In the Add to Map section select Current Mapper and select your map from the dropdown if it isn't preselected. You can also select a symbol you want to use for your points.

    Finally, you need to select the columns holdings your coordinate values. Once done, hit OK to create points for your data.

    Now switch back to your map window in case you are still seeing the browser window. Right-click in the map and select View Entire Layer and select your data file to zoom to the extent of your data points.

    I hope this helps you get your points visualized on a map. From here there are multiple other things you can do to better understand your data.

    You can create a theme based on some categorial values assigned to your data points.

    You can create a standard heatmap to understand where the density of your data points is high.

    I hope this helps
