General information about the service
Helsinki Map Service is powered by SpatialWeb by Sitowise. It offers an interactive way of using maps and inspecting map features. You can navigate freely between different map and data layers, use search functions, change layers and choose what kind of data you want to be shown on the map.
It also offers various functions such as: measuring distances and areas, downloading data, sharing links and creating embedded maps.
It also supports mobile versions, and the UI scales responsively.
We recommend using the service with Google Chrome.
Quick start and navigation
Default language of the service is Finnish, but the user can change the language to their preferred one from the language menu which is located on the top right edge of the page.
The service will open on the start view with the Helsinki Guide Map as the background map and with the view centred on southern Helsinki. The various tools offered by the service will also be immediately visible in the start view. The most notable difference compared to the previous service is that the layer tree is not open all the time; instead, you need to open it through the menu on the left side to browse the layers. The map will show various map tools on a grey background.
Navigating on the map
You can navigate around the main map by dragging it with your mouse. You can move the map by holding the left mouse button and dragging the map to the desired direction. You can change the focus of the map window by clicking on a new location on the minimap in the lower right corner of the page. There is a zoom in/out tool in the upper right corner of the map window. You can zoom in on the map by clicking on the ‘plus’ button and zoom out with the ‘minus’ button.
You can also zoom in and out by scrolling forwards or backwards with the mouse wheel. You can also focus the map window on the desired location by double-clicking. You can focus the map on the north by clicking on the arrow in the middle of the tool.
You can also rotate the map by dragging the N button, signifying north, around the perimeter of the circle. The minimap window in the lower right corner provides a view of a larger area so that the user can better see which area they are looking at in the closer view. The area being viewed is marked with a black rectangle on the minimap. When zooming the map in and out, the rectangle’s size will change with the size of the area shown on the map.
The map view has tool icons on a grey background in the upper left corner. When you place your cursor on a tool, you will see what the tool is used for. Image of the map tools With the Dim Map tool, you can adjust the opacity of the map layers. With the Measure tool, you can measure distances and areas freely on the map or based on the geometry of the target. With the Names tool, you can show the naming information included in vector-form data for the objects. With the Fit View tool, you can adjust the view so that the selected layers are shown on the map in full. With the Coordinate tool, you can receive the coordinates for the selected point in two available formats (EPSG:3879 or WGS84).
With the search function, you can search for objects included in the service. You can perform a search by selecting Search in the menu bar on the left side. You may use either text search or advanced search. Please note that the layer tree will not align itself based on the search results.
Enter the desired object’s address, identifier or first letters or numbers of the identifier in the empty search field. The search will look for the object’s name based on the characters entered. The search uses predictive text search, meaning that the search field will suggest objects that contain the word you have entered.
At the moment, the basic search of the Map Service includes area divisions, place name objects, properties, objects on the service map, buildings and terrain objects, in addition to addresses. Please note! If a street is found immediately in the street name search, the search function will start listing addresses and show the five first matches in the suggestion list. If you want to see the full address list for the street, press either Enter on your keyboard or the Search button on the site.
Search results will open in the search menu as a list. The search will show the objects found sorted by object group. The search results will also be visible in the map window. When you click on an object in the list, the map view will move to the location of the search result. When you click on the object’s symbol on the map, you will see the object’s information, if any is available. If there are multiple objects on top of each other on the map, the map will show a dropdown menu where you can select the desired object. You can centre the map on the object by clicking on the object of your choice in the list of search results. When you click on the table symbol on the right side of the title on the search result list, you will see a table containing the data of the search results. You can place the objects in the search result group on the map view by clicking on the ‘fit’ symbol next to the table symbol.
If you open the search results as a table view, you can export them to Excel or similar by clicking on the download button. You can also choose various other file formats, such as GML, KML, MapInfo or GeoPackage.
You can select the map layers and object groups to be shown on the service on the Layers menu on the left side of the page.
Showing and changing map layers
You can open a map group by clicking on the arrow on the left side of the map group. You can change the background map by clicking on the map’s name on the list. In this case, you will only see the background map in question. If you want to have multiple layers on top of each other, you need to mark the checkbox in front of the desired layer. You can view the maps on top of each other by selecting multiple layers at the same time. When you remove the checkmark from a layer, you will also remove the layer from the map window. You can also adjust the map layers’ opacity freely. You can find the instructions in Now on map.
In the example below, an aerial orthophotograph and a white base map are being viewed simultaneously:
Background information (metadata) of the layers
Each layer has an info button next to it in the map layer menu. By clicking this button the user can open a metadata window, which fetches the metadata from the city of Helsinki's GIS register. The register is updated by the data provider if any changes are made to the layer.
If the layer is a "map set" consisting of multiple layers, it will not have an info button, but the metadata of each separate layer can be accessed through the Now on Map listing, which will show the info buttons.
It is possible to view multiple map features on the map at the same time. The user can select an object by clicking it or by hovering the mouse pointer on top of it. If multiple objects cover the same location, a list will be shown so the user can choose which object's information they want to view. Mouse hover usually shows basic information such as the name of the object, but clicking often opens up an info window which provides additional information.
If a more detailed information window is enabled for the layer, clicking an object will open a window, often to the right side of the browser window.
For example, in the picture below a layer "Buildings (areas)" is active, and the building visible in the picture has been clicked. The information related to the particular building has been pulled from the city's building register.
If there are multiple features on top of each other on the map, a menu will be shown from which the user can choose which object they want to examine. In the example below, multiple layers are active and their names are shown. After clicking the menu, another window is shown which shows only the layers which provide additional information when clicked on their features. In this example three different layers have this "additional information" function attached to them.
The Now on map window is in the lower right corner of the page. It lists all selected background maps and layers. Below this window, you can see the Minimap with a broader map view and a black rectangle showing the size and location of the current view.
Now on map
You can view the metadata of the layers by clicking on the information icon next to the layer’s name. You can adjust the opacity of the layer by clicking on the cogwheel icon. You can remove the layer from the view by clicking on the X icon. The window also shows the drawing order of the map layers, which you can adjust.
You can adjust the opacity of a layer with a slider, which you can access by clicking on the cogwheel icon. On the right side of the slider, you can see the opacity percentage of the layer (1 % being the dimmest and 100 % being the most opaque).
Drawing order of the map layers
The layer on the bottom of the list will be drawn first, and the subsequent layers will be drawn "on top" of it in their order from bottom to the top. The user can change the order of the layers by dragging and dropping them to their desired places.
The print tool can be accessed through the left menu.
Select paper size.
Select paper orientation.
Write a comment if wanted. It will be shown in the printout.
If "Include Now on map" is selected, a list of active layers will be included in the printout.
After the settings are correct, the user can select the area to be printed in the map view. An orange rectangle demonstrating the paper size will appear. Clicking the area into place and then clicking print will create a .pdf file, which can then be printed to paper if wanted.
Download tool can be accessed through the left menu. After pressing the menu button a new tool window will open on top of the map view.
The tool allows the user to download data, if the layers support downloading. The data to be downloaded can be selected with a few filters.
No selection will download all available data.
Visible area will download data currently in view in the map view.
Radius will let the user click on the map to determine a circle buffer around a point, which will show the area from which feature information will be downloaded.
Line buffer will let the user to draw a line with a buffer zone from which feature information will be downloaded.
There is also a free-draw option so the user can draw an area which is shaped however the user wants to be used as the boundaries of the download.
The file format of the export can be selected from multiple different formats. With some of the file formats the creation of the file can take some time, so the user is kindly asked to wait patiently for the file to be available for download. However, if the download is not starting after waiting for a couple of minutes, an error/feedback report is greatly appreciated to ensure smooth operation of the Map Service and its functions.
The Nature information tab is in the tab menu in the top bar of the service.
The button will open the Nature objects button in the left menu bar. You can enter the nature object search via this button. For the search, the Layers menu will open the tabs under the title Environment and nature, the information related to which you can search and filter with this search function. When the Nature information tab is active, the search function will also include advanced search, with which you can search nature objects with various criteria. You can search for specific species or valuable natural sites, for example.
The Plans tab is next to the Nature information tab. With it, a list of as-of-yet unapproved plans will open on the right side of the browser.
When you click on a plan, you can see more detailed information on it. When you open the information, you can see which processing stage the plan is at and by which date you need to file a reminder if you want to influence the plan’s progress.
