GisEditor function and operation
Introduction
Simply
put,
GIS system will
describe the location (place) combines layers of
information, through which information can make you
a better understanding of the location (place).
You can
choose which layers as needed information, such as
the lot to find a better set up shop, analyzing
environmental damage, through an integrated city in
the same crime, that type of crime and so on.
GisEditor
is UCanCode latest
GIS-specific solutions,
the official version provides all of its
100% source code.
All code used in all
VC + + / MFC
development made for the application you develop
any Gis save a lot of
time.
GisEditor
solve the basic problem is: through the layers to
build a multi-level maps, point layer is divided
into layers, line layer and the surface layer.
Surface rendering at the bottom,
line layer Secondly, points plotted in the top
layer.
Single layer can be any database
table to establish the appropriate properties,
property database table can be defined according to
the needs the appropriate database fields.
Database tables stored in the
corresponding data source.
Layer in any of the current pixel
can be free to choose whether the database tables
added to the property, if the increase in, the
association may want to set the corresponding
property value.
A graph element can be set with any
number of related database records.
System provides a complete operating
functions of the layer, such as: add, delete,
change.
Layer in the element attribute data
are free to edit, query.
Layers of the attribute data can be
queried, the output reports and statistical charts.
At the same time the system also
supports importing external
ArcView Shape
files.
GisEditor
database
GisEditor
database is a spatial database.
In addition to type text or numbers
stored in the attribute data, you can also save
point, line or polygon vector data types.
In
GisEditor database,
support for hierarchical structures.
This means: you can set different
levels of
Gis project, each place
different graphical elements.
Of course, can also be calculated on
the basis of statistics and output reports.
GisEditor
database is also time-series databases, all data are
associated with dates.
So you can see the time change in
the attribute data path.
All the properties for the
GisEditor
design data are stored in a database file, the
system default database is provided
Micrososft Access
database, you can use this database file to package
redistribution.
The structure of the database
features and attributes, you can define the project
needs the corresponding data dictionary.
To meet the needs of the project.
Map
Each layer contains a spatial
attribute, such as: administrative boundaries, or a
village location, as well as text or numeric
attribute as a label, for example, in the village,
or in the number of households above the poverty
line name.
You can create a thematic map,
pursuant to the specific data analysis shows the
decision by the layers.
For example, you can be
administrative divisions as a graphic, you can use
different colors to represent the housing and
climate change.
Use of E-XD++
powerful editing features, you can easily modify any
of the geometric characteristics of graphics, such
as the type and appearance of signs and labels
positioning and so on.
In
GisEditor, you are free to
decide whether a pixel into a meaningful database or
not, if placed in the database, the database will be
located under the layer of the primitive definition
of the database table for the corresponding database
record.
Query
Use
GisEditor, you can enter
the conditions to complete the query and report
shows, for example, you can enter certain conditions
show only income less than 1200
yuan village, and its fill color to red.
These features allow you to better
control what to display.
You are free to set the query, for
example: can only select or display the data in
2010 does not belong to the formal settlers
and only in the construction of housing for
families.
Enquiries can also be used for
statistical calculations.
For example, you can calculate the
number of families below the poverty line.
You can also output data histograms,
time series graphs and pie charts.
Image Digital
GisEditor
support including the printing of digital maps.
By providing a comprehensive tool
GisEditor any completed a
map of digital image files.
In the digital, you can import image
files through the way of any image file into the
canvas as a background base map, and then digitizes
it.
Printed maps can be a little
scanner and other devices to the computer directly
to save the image acquisition to the corresponding
image file, then save the image file into the canvas
to complete the digital image file.
Data can be directly encoded.
You can also encode data
Excel spreadsheet, then
import the Excel file.
Projection
Earth and the latitude and longitude
coordinates on a map using Cartesian
(The x, y)
coordinate transformation is called map projection.
Latitude /
longitude coordinates and representatives around the
equator and the Earth's distance from the Greenwich
meridian difference, when we use the map displayed
on the computer screen or map the spherical
coordinates (D) must be converted to plane (D
conversion) coordinates for specific areas of the
earth.
This is the
projection.
GISEDITOR data storage and
the corresponding coordinates (x,
y) of the associated primitives.
When
the data in latitude
/ longitude converted to
x, y coordinates using the
default stored in the database before the projector.
When you import
GISEDITOR data, it will automatically
determine whether the latitude /
longitude data, or x, y
coordinates and convert the data needed.
A
UTM
Projection
When you first
GISEDITOR create a new database, you will be
told not define the default projection.
Choose to define a
new projection.
Operation is as follows:
1),
select "Database | Map
Projection Settings" submenu.
2)
can be defined in the following dialog box, map
projection.
Then the following dialog box will
appear:.
In this dialog box, as you need to
set the appropriate parameters.
Creating thematic
maps
Thematic map is in color or
line styles and symbols unified map.
For example, the size of the village
sign on behalf of its population.
Create thematic maps, the first
layer added to the map included spatial attributes
(line
/ polgons or coordinates)
and the label is mapped theme.
Layers dialog box from the map, you
can add a new layer and select the surface type, you
can also use the cover illustration shows the
shapefile file.
Note: Add a layer, make sure
you have configured the appropriate data source, and
set up the appropriate map projection.
Data Dictionary
Data dictionary defines the data
structure GISEDITOR
features and their properties database.
This is similar to the
relational database tables and columns.
Of course there is some difference
and relational databases, including:
1),
pixel level can be arranged, the property features
of the data field may be his son.
For example, the
'village' may have a
parent feature 'area'.
And text attributes (numbers, text,
notes, etc.) data, but also can have spatial
attributes (coordinates, polyline
/ polygon or geographic coordinates, links,
image files), to be mapped.
For
example, there may be a county boundary line type
/
polygon attribute field.
2),
all features have a default name.
For
example, the 'village' is
probably the name of 'Third
Stream', 'river', etc.
All attribute fields are associated
with a date.
For example, the 'population'
and changes over time.
Any property fields are likely to
change over time, such as: administrative
boundaries, rivers, etc.
The structure of your data dictionary
will reflect the information you want to store and
use the output of the report content
GISEDITOR.
Usually this is the simplest
structure of the database to reflect your
administrative structure of the project area.
For
example, you can create
For the
'province', 'City', 'county' and
'family' and so primitive,
for each pixel, you create the attribute data tables
to store their information.
And automatically has a name
and a date attribute.
For example, for a
province you can create a
'boundary line of
type' attribute
/ type of polygons and a
'center'
Field types of attributes and
coordinates.
You want to store attribute
information, such as socio-economic data,
environmental indicators, or demographic data can be
stored as part of the defined function, that is
'family', 'villages'
and so on, meaningful set of data.
For
example,
'Population', 'family index', 'the village
community organizations'
and so on. Database may
be arranged pixel level, such as the
'village' has superior properties
'county'.
For these primitives, you can
define the corresponding number of attributes.
For example,
'Population'
may have a property type -
the number of the total population and the
'digital type
- family.'Family
indicators' may have
attribute' number of children in primary
school - the type number.
Note: Due to the
properties of the data dictionary hierarchy, may be
inherited, so only need to define one.
For example, if your target is not
necessary to store the family is also stored as the
municipal index statistics. Specific statistical data can be
calculated by querying the consultation.
The following
is a basic guide
GisEditor:
1 Create
a new database

This layer is the layer code string
associated with the database, if you want the layer
with an existing database table associated in the
drop-down list to select the encoding of the table.
6, for the layers to
create the database tables
In GisEditor
in any layer can establish the corresponding
attribute data table, if you want to create the
table, the canvas on the left of the layer list,
select the appropriate layer name, then click the
right mouse button, select "Database Connection"
sub-menu, dialog box appears as follows:
And then create the corresponding
database field functions, including the properties
of space field list (line /
polygons, numbers, etc.).
In the lower part of the dialog box
you can define all the attributes required of the
database fields, such as adding new fields, updates
the selected fields, and delete database fields and
so on.
If you need to add new database
fields, the operation when the first edit box on the
right, enter the description field, type, etc., and
then click the above "Add" button.
Description: built on top of a
layer hierarchy.
Enter the name of
the layer, for example:
'province', as this parent in the hierarchy
function
'"Untitled' and
relationship between superiors.
Once the functions and data
dictionary definition of your property, you can
input records, or import the data into the database.
