Mapinfo Basic Concepts

Mapinfo tableA table in Mapinfo is different from a common one. It is a logical table, but composes of multiple physical files. A table in Mapinfo includes:
Data table: It includes graphical information or not. It composes of rows and columns, wherein, rows are for different record and columns for the corresponding fields. Raster table: It is different from data table and has no records, fields, index and so on. It is an image that can only be displayed in the Mapinfo window.
Here, table in Mapinfo refers to pure data table or
table containing both data and graphical
information, but excluding raster table.Note:
Mapinfo Basic Concepts
Mapinfo table consists of the five
types of files listedxxx (file name).tab: used to describe
data structure
xxx (file name).map
can be either a pure data file or a
data-graphical information joint file.
xxx (file name).id
An index file created when using
[Find] command.
xxx (file name).ind
When a table contains graphical
information, ID file acts as the
index of the graphical files to joint
the data and the graphical
information.
xxx (file name).dat/xls/dbf
Database file as the data source of
an Mapinfo table. Can be either
EXCEL or FOXBASE files.

Mapinfo Basic Concepts
Mapinfo workspace Workspace is a set including multiple tables in a map window. Here, a set is one that composes of multiple paths to open the relative tables instead of that containing multiple of tables physically. The user can save the current workspace after opening all necessary tables, and then open the workspace directly if those tables are required again next time.

Mapinfo Basic Concepts
RasterRaster is a kind of bitmap since it is composed of numerous picture points. Activate the
raster first before creating a vector map. Mapinfo raster supports the following types of files: xx*.gif, xx*.jpg, xx *.tif, xx *.pxc, xx *.bmf (windows bitmap), xx *.tda, xx *.bll (spot satellite map).
Use of rasterAs background of Mpinfo mapAs an independent map As a reference for creating a vector map

Mapinfo Basic Concepts
Map layerGenerally, a map includes various
kinds of information, but only one kind of information is concerned during the analysis for a specific target. Therefore, it is recommended to create different layers for information of different kinds to make convenience for the specific analysis.
Generally, a layer corresponds to one Mapinfo table, but it can also corresponds to multiple tables by seamless map layers
Layers can be classified into cosmetic layers, seamless map layers and standard layers.
Layer control includes the following options (in the form of checkboxes): Editable, Auto Label, Selectable, Visible.

Mapinfo Basic Concepts
Map layers
Layer Control“Remove“
Remove one or more layers from
the map. In fact, the act only
removes the layer from the current
windows instead of the memory,
and they can be restored by
clicking <Add> in the [Layer
Control] dialog, unless they have
been removed by clicking
[File/Close Table].
“Add”
Add one or more layers to the map
window. Choose from the listbox of
opened tables.
“Label”
Available only when the selected
layer is not a Thematic layer or
Raster layer. Click to open the
Label Options dialog. Use this
dialog to specify label attributes for
map layers.

“Display”Use this dialog box to specify display attributes for map layers.
“Thematic”Choose to display the [Modify Thematic Layer] dialog box. Use this dialog to modify the attributes of a thematic map.
“Reorder”Use the “UP” and Down” buttons to modify the relative pisition of the current layer

Mapinfo Table MaintenanceMapinfo table maintenance
Maintain table structure : [Table/Maintenance]
Update data in a table : [Table/Update Column]
Combination : [Table/Combine Objects using Column]
Rename table : [Table/Maintenance/Rename Table]
Table import/export : [Table/ Import/Export
Here, we only give an introduction
to “Update Column” and use it as
an example for other operation.Wednesday, April 12, 2023www.tempustelcosys.com
Mapinfo Table MaintenanceUpdate data in a table using the [Table/Update Column] menu Update Column allows you to change a column's value based on its own data or data from another table automatically, it will alleviate your work. This is done by using the special joint between two tables, usual the cell name, to update the data in one table or import the data from one table to another
Operating steps: Create a table (usually using
excel), and input the data to be added and the joint data.
Open the two tables in Mapinfo.

“SQL Select” and “Find”
SQL SelectStructure Query Language (SQL)
provides a powerful query platform that makes a feature of simple language and convenient operation. SQL platform presents a graphical dialog to facilitate selecting data source and query conditions, and generates SQL sentence before executing the SQL sentence. Finally, it generates a temporary table to display the results, as shown below.

Label
In Mapinfo system, the user can specify
the content, position and style of labels.
The user can either label the object
with the content of a particular column
in a table or create an expression to set
up and display custom labels.
By choosing label lines, the user
can control whether a line or arrow
connects the object you want to label,
or position the label to fall in a
particular location relative to the object.
The user can control the look of the
label by choosing different fonts.
Operating steps:
Right click in the [Map] window to
select [Layer Control], and then select
the layer to be labeled and click
<Label>.

Register Raster Image and Create Vector MapRegister raster image
Raster image is some kind of bitmap. Register raster image can make it contain both longitude and latitude. It is recommended to choose at least three special points, such as the road cross, school, hotel and so on, and then measure both the longitude and the latitude with GPS for them. The points can’t belong to the same straight line. For the points, the more the better.
Wednesday, April 12, 2023www.tempustelcosys.com

In the Mapinfo, select [File/Open Table] to pop up the [Open Table] dialog. Select [Raster Image] and then select a file, click <Open>. In the popped up dialog, click <register> to pop up the [Image registration] dialog box. Click <projection> to pop up the [choose projection] dialog box. Select “Longitude/Latitude” in the [Category] pull-down list. For the [Category members] pull-down list, it is set as per the projection mode selected (i.e. Longitude/Latitude (WGS84). Finally, click <OK>.

Operating stepsOpen the raster image file
configuredSelect [File/New Table], and then
make sure to check [Add to Current Mapper] in the popped up dialog. Click <Create> to pop up the [New Table Structure] dialog box. Following the above, click <Add Field] and then input the field information including “Name”, “Type” and “Width”. Add more fields in this way.
Then click <Projection> to select “Longitude/Latitude” (the same projection category with that of the raster image file).
Finally, click <Create>.

Register Raster Image and Create Vector MapOperating steps:
In the [Create New Table] dialog box, input the file name before click <Save>. Then, two tables can be viewed in the title bar of the [Map] window. One represents the vector map, and the other represents bitmap. Right click in the [Map] window to select [Layer Control] to make sure that vector map is editable
Drawing the vector map as per the raster image with the Drawing Toolbar. Select the polyline and right click to select [Object /Smoth].
Save the vector map in the following four files: XXX.dat, XXX.tab, XXX.id and XXX.map. Then it is available either in the Mapinfo or others.

There are three methods to output the measurement results after drive test analysis. Copy the screen and then do
some specific process Use [File/Save Window As]Use [Window/New Layout
Window]Layout window is preferred to output the analysis result. It uses WYSIWYG (What you see is what you get) manner. This makes it more effective and accurate comparing to other two.Select [File/Save Window] of the layout window to output the measurement results, as shown below.
