Creating a project

How to create your first project on the GISCARTA platform

Basic steps to create your web map

  1. Upload your data or select which GISCARTA datasets you want to use.

  2. Create a new project in the "My Projects" section.

  3. Add data to the project.

  4. Set up the layers.

  5. Select and configure the necessary widgets.

  6. Save and publish the project.

Add user data

Before you create your project, you’ll need to decide what data you want to use on your map and upload it to the platform.
You can upload data in GeoJSON, Excel, or KML formats, or as a ZIP archive with a SHP file, as well as raster data in TIFF format.
To download files, drag and drop them into the designated field or select a file using the file explorer. Next, fill in the following fields:

  • File name — the name that will be displayed in the data directory

  • Description — a more detailed description of your data

  • Tags — option to add a tag to facilitate searching and navigation in the data catalog. Tags are filled in by typing text and pressing Enter

If you are uploading an Excel file, you will need to fill in additional fields:

  • Specify the columns with object coordinates: X — longitude, Y — latitude

  • Select the projection from the drop-down list: 1) 4326 (for geographical coordinates) 2) 3857 3) 3576 4) 3031 5) 5940 6) 3573

After the file has been successfully uploaded, a data upload notification will appear in the lower right corner of the screen.
The GISCARTA data available through your subscription is already in the list of available data. You can add it to the web map when you create projects.

Add data from external sources

The user can also upload data from external sources. Currently, these can be layers published on GeoServer or ArcGIS Server, or any WMS or WMTS service. The data will be displayed on the map as a WMS or vector layer.
To connect an external data source, you need to first select the appropriate type of service: GeoServer or ArcGIS Server, then enter a link that leads to a list of services, for example:

Next, you need to click on the Connect button to connect to this resource and get a list of available services. After receiving the list of layers, you need to select those that will be saved in the data source (this can be one or more layers).
Next, you need to specify a name, description, and tags for the new data source and click the Save button.
Now this source will be available for adding to the map as a WMS or vector layer.

Layer display options

How to set up visualization for your data on a map

How to begin setup

The GISCARTA platform allows you to easily and conveniently configure the display of your data on the map. You can do so in the "Edit layer" menu.
To access, click on the three-dot icon to the right of the layer name and select "Edit." This displays a panel where you can configure the basic settings.

Main settings

In this section, you can:

  • Rename the data layer by typing its name in the corresponding field

  • Use the slider to adjust its transparency (when the Layer transparency widget is enabled)

  • Enable or disable identification (displaying the layer information window)

  • Select the displayed field (its value will be displayed in the information window title)

Infowindow

In this tab you can:

Turn on or off the information window for the layer

Specify the title of the information window (a combination of text and layer attributes)

Specify the display parameters of the information window (on the map or in the sidebar). When specifying the display of the information window in the sidebar, all links that lead to images will be displayed as an image gallery at the top of the information window (see Figure 3).

Configure the content of the information window. The following types of content are available: Table, Button, Text, Iframe

When setting up a Table (see Figure 4), you can turn attributes on and off, affecting their display in the information window, drag and change the order of attributes, and set aliases for them.

When setting up a Button (see Figure 5), you can specify a single link for all objects or take a link from an attribute. You can also customize the button color, text, and button text color.

When setting up a Text (see Figure 6), you can use the standard constructor and write custom text using object attributes.

When setting up an Iframe (see Figure 7), you can specify a single external source link for all objects or take a link from an attribute.

Filtering

This tab allows you to configure filtering by attribute value, which will then be available as a set of filters under each layer in the "Layer list" of your project.
Click on the "+" icon to add an attribute to filter by. Then, next to the added attribute, click the "Settings" icon and configure the filtering settings.
To do so, set an attribute, create a filter name and choose a filter type (see Figure 3):
for the selected layer by selecting the appropriate option:

  • Checkboxes — multiple values can be selected

  • Radio buttons — one value can be selected

  • Range — it is possible to select a range of values to display

Add the values of the fields you want to be filtered (using the "Add value" button) or load unique values automatically (using the "Add all" button).
Enable or disable the default filter for each field by clicking the corresponding checkbox.
It is also possible to delete the added filter value by clicking on the "Trash" icon.
To display filters, click the filter icon next to your layer name, and the filters you have set will be displayed in the opened block (see Figure 4).
Pressing the "Reset" button resets all selected filter values.

Styling vector data

Here you can set the display style of attributes for the selected layer by choosing from one of the following options:

  • Single symbol

  • Symbol by one attribute

  • Symbol by several attributes

  • Pie chart

  • Heatmap

Single symbol
This style is applicable to all spatial elements and refers to a single display for all objects in the layer. It is possible to customise the symbol, size, fill, border (see Figure 1). For point layers, you can also upload your own symbol in svg format and up to 400kb in size (see Figure 2).

Symbol by one attribute
This style is applicable to all spatial elements and refers to a display set by one of the layer’s attributes. To do so, select an attribute from the drop-down list and then set up the styling for the values of this attribute.
For text attributes, it is possible to automatically load all values by selecting the "Unique values" method and clicking the "Set" button (see Figure 1).

For numeric attributes, you can set intervals using the following methods (see Figure 1):

  • Equal intervals is a method that will divide the range of values into equal-size classes. For example, three classes for the range of values from 0 to 300 will be created with the following ranges: 0 — 100, 101 — 200, 201 — 300.

  • Equal number (quantile) is a method that will split the range of values into classes equal to the number of objects within each class.

  • Natural Breaks (Jenks optimization) is a method that will split the range of values into classes, the differences between values within which will be maximal.

Now you can set the symbol style for each of the set values separately or apply the general settings to all values by clicking on the "Gears" icon next to the word Symbol (see Figure 2). General settings include selecting a palette or fill, and setting the look and size of the symbol.
You can also specify value aliases for the Legend layer.

Symbol by several attributes
This style is applicable to Point layers and refers to a display adjusted by several layer attributes. Here you can set the display of attributes in three categories (see Figure 1):

  • By symbol

  • By color

  • By size

To do so, select the attribute for each category and the way it will be set: Unique values or interval types (see Symbol by one attribute). You can also configure the values and styles manually.
You can also specify value aliases for the Legend layer.

Bivariate map
This style is applicable to all types of geometry, but is most often used for polygonal layers. In this case, stylization is based on 2 numeric attributes, for each of which 3 intervals are generated and, accordingly, 3 colors. Then these colors intersect and a 3x3 matrix with 9 colors is obtained. In other words, the bivariate choropleth style shows the dependence of two attributes on each other and allows you to clearly represent this on the map. In the style settings (Figure 1), you need to select numeric attributes, interval types (see Symbol by one attribute) and colors. You can also customize the axis labels and change the border, symbol and size (if a point layer is configured) by clicking on the gear. Figure 2 shows the legend of this style on a map.

Pie chart
This style is applicable for point layers and refers to displaying a chart at a point that is set by several layer attributes. Here you can set the point size (see Figure 1) based on a numeric attribute by selecting one of several options: Unique values or interval types (see Symbol by one attribute). In addition, you can specify the numeric fields used to construct the pie chart (see Figure 2). The sectors are divided according to the share of each of the attributes in the total for each object (see Figure 3). User can also customise the type of chart: Pie, Donut, Bar. And choose a style: 2D or 3D (see pictures 4, 5, 6)

Heatmap
This style is applicable to point type geometry and allows you to configure the display as a heatmap. When configuring this style, you can choose a numeric attribute for the degree of change for the point color intensity. If an attribute is not selected, then all points are set to the same intensity and a heatmap is created based on the point density distribution. If an attribute is selected, each point will be weighted by the attribute’s value. A point weight can vary from 0 to 1. If the value is greater than 1, then the point weight is set to 1. If the value is less than 0, then the point weight is set to 0. Therefore, an attribute with a weighted value between 0 and 1 is needed in order to get correct results.
You can also change the gradient palettes, the point radius and its blurring. In the "Alias" column, the caption for the Legend layer can be set.

Styling raster data

Here you can customize the raster data display style by selecting the appropriate option:

  • By gradient

  • By band

By gradient
This styling type is used to stylize rasters by 1 selected band using a customized gradient (see Figure 1). You can change the ranges for the specified gradient (including making the ranges discrete) (see Figure 2). You can also change the display by specifying colors and intervals manually (up to 5 intervals are available in the online version) (see Figure 3).
By band
This style is used to stylize multi-band rasters (see Figure 4). You can choose which band corresponds to the Red, Green, and Blue spectrum in the RGB model. And also change ranges for each channel.

You can also customize the following characteristics for all images (see Figure 6):

  • Hue

  • Saturation

  • Brightness

Labels

In this tab you can enable and set the style of labels according to the selected fields or any text. To do so, switch the activation button to the corresponding mode. Then select fields (attributes) from the drop-down list that will be used for labeling features and set the format of the Label: font, size, color, text position relative to the object, halo parameters. You can use the \n character to break a line in a Label. For line features, settings for the position and alignment of the label are also available (top, bottom, intersecting, at the beginning, at the end and in the center).
The user can also configure the visibility of labels depending on the zoom level of the map.

The end user will be able to enable and disable object labels by clicking on the Style icon next to the layer name (see Figure 2).

Legend

This tab is used to set up the display of the legend on your map. Click on the Legend widget icon.

Fields

This section configures the list of fields that will be shown in the Attribute table.

In this section, you can rename attributes by specifying their aliases in the right column, if necessary.

Clustering

This section is available only for Point layers added to the map as vector data.
Clustering makes it easier to view a Point layer with a large number of objects. Once clustering is enabled, object points are grouped into clusters when zooming out, increasing map readability.

In this tab you can:

  1. Enable or disable clustering.

  2. Select the clustering algorithm ("Simple grouping" or "Pie Chart")

  3. Set the cluster color (with the "Simple grouping" algorithm)

  4. Configure the cluster size

When choosing the "Simple grouping" algorithm, the color and size of the cluster are set by the user (see Figure 1).
When choosing the "Pie chart" algorithm, the user must have styling configured for one or more attributes. The color of a sector of the cluster pie chart will be automatically imported from the "Styling" section. The size of each sector will correspond to the number of points in the cluster with the respective attribute value.

The end user will be provided with the option to enable and disable clustering by clicking on the Style icon next to the layer name (see Figure 5).
