Bit Map 7.0 Released

Postby Son of a Beach » Thu 02 Sep, 2021 2:47 pm

'Bit Map' has returned to the iOS app store at last, and version 7.0 has been released today. It can be found on the iOS App Store at:

https://apps.apple.com/au/app/bit-map/id1560781471

(I think it should also run on AS Mac as well (but not Intel Macs), but I've not had an opportunity to test this yet.)

For those who don't know...

Bit Map was the first iOS mapping/navigation app to provide users with the means to use their own arbitrary maps on their iOS devices (in 2009). At the time, other apps only worked with maps that were specifically designed for the app, or with maps that were built into the app. With BIt Map, you can use any map image, such as a photo or scan of a paper map, and georeference it on the device, or use a raster image that is already georeferenced.

Bit Map was later replaced with another app, and that app was later sold to another developer, who sold it on, and it was never updated, and that other app no longer runs on current devices.

So Bit Map has been re-written from scratch, and includes all the features of the previous version and the other app, as well as several improvements, the most significant of which are:

  • Use of online map services, such as WMTS, TMS, XYZ. (Has Open Street Map configured by default.)
  • Can read vector data from many different formats, and can write to several formats as well, including: GeoPackage (default), Shapefiles, GPX, file geodatabase (read-only), KML.
  • FOUR methods of georeferencing raster images, now including arbitrary control points
  • Highly customisable layer styles (symbology)
  • Lots of options for sharing data, maps, styles (AKA symbology) and settings with other users

This new generation of Bit Map is more of a GIS with a mapping/navigation focus. Some of the features planned for future releases include the ability to create/edit polygons and lines. At present, polygons are read-only and lines can only be created using the tracking feature. This GIS approach means that there is a little more data-management overhead than earlier versions, but it is much more flexible in what it can do, and the maps that can be displayed (ie, multiple rasters, plus multiple vector layers can be displayed on a single map, in which-ever layer-order is desired.)

The Bit Map home page is at: http://nixanz.com/bitmap/
The (almost-but-not-quite complete) user guide is at: https://nixanz.com/bitmap/user-guide/

Enjoy!

I forgot to mention that the latest version of MAPC2MAPC can be used on Windows computers to georeference, tile and/or mosaic map image files into the new Bit Map 7 format. Although this can all be done on the device, it can sometimes be quicker and easier to manage this task on a desktop machine with a larger screen and more powerful processors.

(For Macs, the new AS Macs can run Bit Map natively, and do the work that way. Although I've not actually tested it yet, as I don't have an AS Mac.)

The home page for MAPC2MAPC is at: https://www.the-thorns.org.uk/mapping/

The developer tells me:

MAPC2MAPC has two ways to make BitMap7 files.

For a single image file or map, you load the calibrated map (or load an image and calibrate it) then choose File>Write BitMap7 for iphone. then save the 'bm7' file in the iCloud Drive folder that can then be moved to the iPhone and unzipped.

If there are several maps of the same area at different scales and/or maps of adjacent areas that you want to combine into one they can be built into a single BitMap7 file.

For each of the maps, open the calibrated map (or open the image and calibrate it) then choose File>Write map for Mobile device select MBTiles Sqlite and specify the zoom levels you want. Be sure to check the 'Write atlas directly..' box at the bottom left. Write the maps to the same MBTiles file replying Yes to the 'Merge with existing file' messages.

When you have all the maps you want, choose Utilities>Convert MBTiles to BitMap and save the bm7 file as above (Note this function does not appear for unregistered versions).

…and Bit Map Lite (free version) has now been uploaded to the App Store and will be available very soon (once I can convince Apple’s reviewer that the word “tracking” used in several parts of this app has nothing to do with sharing user data with other apps and web sites!).

A ‘Pro’ version will also be available as an in-app purchase with the next release. (Not available in the ‘Lite’ version.)

FREE VERSION:

Bit Map Lite ( FREE version ) is now available on the app store at:

https://apps.apple.com/au/app/bit-map-lite/id1584262856

The limitations of the 'Lite' version are:

  • Maximum of 3 online map services and/or offline data stores can be managed in the app (no limit to the number of layers that these services or data stores can contain)
  • Tracking always uses the ‘WGS 84’ (EPSG:4326) spatial reference system (default of most GNSS/GPS devices)
  • Settings cannot be locked with a password
  • Cannot use the 'Pro' level features (see below)

Although there are ways to work around the first two items, for people who are willing to figure it out. ;-)

FREE MAP SERVICES FOR BIT MAP (inc LIST for Tasmanian maps, and some other state government map services):

There's a list of map services that you can easily add to Bit Map (standard or 'lite') at:

https://nixanz.com/bitmap/resources/map-services/

If you know of others, please send me details, and I'll add them to the list.

I know that a lot of forum members use Tasmania's (DPIPWE's) LIST Map services. They are included in the list linked to above (and are what I usually use in Bit Map).

Just copy/paste the URL into Bit Map, and you're away (or see the more detailed instructions at: https://nixanz.com/bitmap/user-guide/on ... directory/ ).

PRO VERSION:

There is now a 'Pro' version available as an in-app purchase in the standard version (not in the 'Lite') version. The Pro version allows adding features to arbitrary layers ('+' button on the Map View), not just to the waypoints layer. This only works for point layers for now, but the ability to add new lines and polygons from the Map View is planned.

In future some advanced features may be added to only the Pro version but other (less advanced) new features will be still be added to the standard (and Lite) version.
