PDF Maps is a fast and powerful geospatial PDF, GeoPDF®, and GeoTIFF reader for most Android devices running Android 4.0 and higher. It renders maps quickly and features intuitive multi-touch gestures for easy navigation. With PDF Maps, you can download and open saved maps, pan, zoom, use GPS to locate yourself on the map, drop multiple placemarks, add attribute data, and measure area and distance. The easiest way to get maps is to download them directly from the PDF Maps Store.
Geospatial PDF files are PDF documents that contain geospatial information such as real world location and/or GIS attributes. Geospatial PDF documents can be created in many GIS applications such as ArcGIS and Mapinfo and from within Adobe Illustrator and Adobe Photoshop with the aid of the MAPublisher and Geographic Imager plug-ins, respectively. The geospatial data contained in a geospatial PDF document may be accessed and used (for example to locate a specific point or measure distances) without the aid of any additional plugins, using tools found natively in Adobe Reader 9 and Acrobat 9.
GeoTIFF and JPG formats are also supported. GeoTIFF is a commonly used image format to store geospatial information. JPG format doesn't store geospatial or coordinate system information, so it must have external reference files: either TFW & PRJ or JGW & WKT. All three files must be placed in a ZIP file when importing to PDF Maps.
The PDF Maps Store contains spatially referenced maps from around the world including USGS and Canadian Topographic maps. The PDF Maps Store can be accessed directly through the app where in-app purchases can be made. Maps can be downloaded for free as well. Vendors can register and sell their maps on the Map Store. See more info about the PDF Maps Store.
The following is a list of supported gestures and what they perform:
Tap the GPS button to use the built-in GPS to view your location in real-time. Tapping the location icon once will locate you on the map while tapping the location icon again will focus the frame on your location as you move around the map. This only works if you are physically within the geographic extents of the map that you are viewing. The status Not on map appears if you are not within the extents of the map.
Assuming that you are within the geographic extents of the map, tap the GPS button to locate yourself, then tap the Drop Placemark button. Placemarks are also known as pins (used interchangeably).
First, move to a position you want to drop a placemark at, then tap the Drop Placemark button. A crosshair in the middle of the screen identifies where the placemark will be added. Pan the map again and simply tap the Drop Placemark button to drop another placemark. Tap the Map Features List button to see a list of all placemarks on the map.
Tap a placemark to show its label. Then tap the placemark label. On the Edit Map Feature screen, tap the thumbnail of the placemark (beside the placemark title) and then choose a different pin colour or choose an imported icon. The placemark will update with the chosen colour or icon upon returning to the map.
Tap a placemark to show its label. Then tap the placemark label. Tap the Edit Folder/Attribute Schema icon (pencil) to view more settings. Under the Attribute Schema section, tap the + icon to add a new attribute or tap an existing attribute to edit it. Enter or edit the Field Name, Field Type and, if necessary, add items to a Pick List. Attributes and fields may be edited at any time.
Tap a placemark to show its label. Then tap the placemark label. On the Edit Map Feature screen, tap the Description heading and type into the text area. Descriptions or notes can be used to record information.
To add photos to a map, tap the Tools button and tap Plot Photos. In the photo browser, choose an existing photo. Note that only geotagged photos can be added using this method. To add photos to a placemark, line or track, tap one to show its label, then tap the label. On the Edit Map Feature screen, tap the Photos heading. Tap the Camera icon to add photos using the device camera or tap the Gallery icon to choose an existing photo.
Tap the Map Tools button, then tap Record GPS Tracks. On the map, tap the Play icon to begin recording. Your movements will be recorded when the app is open or when it is minimized to the background. Tap Done at any time to stop recording and to automatically save the track to the Tracks folder. For more detailed track information, tap the track to show its label, then tap the Show Graph heading. In the Track Statistics screen, the distance, elevation change and time are displayed. Tap Speed or Elevation to see its respective graph.
When viewing a map, the map coordinates are displayed at the top of the screen. The coordinates are designated by the crosshair in the middle of the map view. By default, the latitude and longitude coordinates are listed. Tap the coordinates to change the display format to WGS84, Northing/Easting, or Military Grid Reference System (MGRS).
Tap a placemark to show its label. Then tap the placemark label. The coordinates are listed beside the Location heading. Tap the location values to edit them (note that new values do not update the actual placemark location on the map).
Tap the Map Features List button, then tap the Export Map Features button. In the Export Map Features screen, specify a file name and format (KML). In the Send To section, tap the option to choose either SD Card, Email, or Dropbox. Finally, tap Export to send the file to the chosen location. Tap Export Schema only to send the schema of the map to the chosen location.
Tap the MAP Features List button. In the Map Features screen, tap Placemarks folder to open it. Tap the check box beside a placemark to select it, then tap Delete. Alternatively, an entire folder containing placemarks or map features can be deleted using the same steps. To delete a placemark while editing it, tap the Delete icon.
Tap the MAP Features List button. In the Map Features screen, tap the check box beside a folder or map feature. In the top menu, tap the Visibility icon (eye). A folder or map feature that is not visible will have a faded/transparent icon. Use the same step to make the folder or map feature visible again.
Simply tap anywhere on the map once that's not a label and the map feature labels will hide.
Tap the Map Tools button, then tap Measure Distance or Area. Tap the Measure Area/Distance icon to toggle between the respective modes. Move the crosshair to the initial measurement point, then tap the + icon to begin. Pan the map away from the initial measurement point. The measurement values are displayed at the top of the screen. Tap the + icon to set another measurement point. The measurement updates as more points are added. Tap the x icon to delete the last placed measurement point. Tap Save to save the line.
In the Measure Distance or Measure Area mode, tap the Options icon in the upper-right corner, then choose a new measurement (feet, kilometres, metres, miles, nautical miles, minutes (walking), or yards. Under the Custom Units section, tap the + icon to add a new unit (e.g. m/s, ft/s, km/h, mi/h).
Tap the GPS button to enable the GPS mode, then tap the GPS button again to enable the compass mode. In Compass mode, a floating compass orients towards north (red tip) and rotates the map as you turn. To exit Compass mode, tap the GPS button once more or pan away from your location.
The option to render in high resolution is not supported yet, but will be available in a future release.
Tap the Map Tools button, then tap Find Places. Enter an address or keyword to search for and tap OK. Use the arrows to cycle through search results. Tap Done when finished searching and optionally save the results to a folder.
Tap the Placemarks List button, then tap the Import Placemarks button. In the Import Placemarks screen, choose to import placemarks from SD Card, from Dropbox, or from the web. Upon import, placemarks are added for each location specified in the KML file.
An attribute schema is a set of pre-defined properties that are applied across an entire folder of KML points. Their primary purpose is to allow quick and efficient data collection without having to define them point by point.
Create and edit attribute schemas in a folder in the Map Features List. Tap the Map Features List button, then tap the checkbox beside a folder and tap the Edit Folder/Attribute Schema icon (pencil). In the Attribute Schema section, add or edit attributes including the field name, field data type and create pick lists. You can also set the folder with a default icon and as the current folder so any placemarks dropped will automatically have the schema applied to it.
Yes you can! Attribute schemas exist inside the folders you create them in. By creating multiple folders you can have multiple schemas on the same map. Just be sure to change the Current Folder setting to match the attribute schema you want.
You can share attribute schemas in the same way you can share KML/KMZ points. Tap the Map Features List button, then tap the Import or Export button. In the Export Map Features screen, choose to Import Schema Only or Export Schema Only. Once an attribute schema is imported, it will appear as a folder in your Map Features list.
