TransektCount is an Android app that supports transect counters in nature preserving projects according to the European Butterfly Monitoring Scheme methodology. It allows a species-specific counting per transect section.
- Data recording is organized according to a single transect inspection. That means, you will use a fesh database instance per inspection by clearing the current database or importing a prepared basic Database.
- It contains a prepared basic database with some of the expected species as a starting point.
- Databases can be individually created and adapted within the app regarding meta data, transect sections and expected butterfly species.
- Transect sections can be selected manually (automatically via GPS has been abandoned due to faulty performance).
- There are editors for the transect sections to setup or adapt its species,
- for meta data to prepare an inspection and
- for species remark or bulk count entry.
- The counting page has a scroll-list to select species
- Counts are recorded per internal/external counting area and here each with separate counters for ♂, ♀ or undefined, pupa, larva or egg.
- Results are prepared for easy readout to transfer them to science4you or Tagfalter-Monitoring Deutschland entry masks.
- Results are shown with meta data, remarks, totals and species results per section.
- Results may also be exported in SQLite- or CSV-format and transferred to a PC for your own processing, e.g. by importing a csv-file into a spreadsheet.
- The integrated help contains a detailed userguide.
The app demands for
- storage access permit which is needed for im-/exporting the counting data and
- the permit to keep the device awake.
The device screen should have a minimum resolution of 1920 x 1024 pixels. The app is usable with Android version 7.1 (Nougat) or newer.
