MAST is a suite of tools and approaches that supports the collection and management of land rights and resource information. It integrates mobile applications and a web-based data management platform with participatory on-the-ground approaches. The mobile application enables field teams to collect spatial, attribute, and multimedia data about land parcels and natural resources. Data is collected and stored on mobile devices and transferred to a cloud-based platform for data processing and management. This platform provides advanced functionality that has been reviewed, processed, and approved for the preparation of land ownership certificates.
Data Management Platform
The MAST data management platform consists of four core components that allow users to establish a survey project, define data that is to be collected in the field, process and manage data, and generate and print land rights certificates:
MAST Mobile is an Android-based application that can be used to capture land rights information in the field. The MAST Mobile application provides an intuitive user experience for querying map layers and capturing spatial, attribute, and multimedia information.
Key Features (Why Use MAST?)
Use the mobile app to map community land parcels or common resources using GPS or touchscreen. MAST records attributes of the land and occupants in the field, online or offline, and then syncs to the data management platform.
After parcels are recorded and finalized, land administrators can keep them up to date through a simple registration system. Land can be sold, leased, mortgaged, subdivided, and gifted through a set of easy to use workflows. Administrators can log official paperwork with the transactions.
Land administrators can connect their preferred desktop GIS software, like QGIS or ArcGIS, directly to the MAST database for editing and error correction. MAST will prevent restricted edits and can even work offline with the right set of plugins.
MAST allows users to easily collect spatial data in the field using GPS on a mobile device, as well as GPS receivers connected to devices via Bluetooth. If a project requires higher GPS accuracy than is available on board a mobile device, external GPS receivers can be configured to work with MAST.
MAST works seamlessly in offline mode with spatial data and its associated attributes stored in an SQLite database. MAST allows users to synchronize data collected while in offline mode to the web-based data management platform. This can be done manually or at a frequency determined by the user, whenever connectivity is available.
MAST adheres to the Land Administration Domain Model (LADM) and captures location information of geographic objects and selected property, parties, and rights information. The data model facilitates the customization of MAST for different contexts by allowing users to define and add attributes to predefined tables.
MAST allows authorized users to upload data to the data management platform from a variety of mobile devices. MAST also checks attribute data for inconsistencies and validates spatial data according to set rules. Validation errors are tracked and displayed in MAST for project administrator follow-up and correction.
With MAST, users can read, manage, and store spatial and attribute data that has been collected in the field. Authorized users can also review, edit, and approve the data related to each land record, along with their attributes and multimedia information.
Web Visualization and Editing Functionality
With MAST, users can view project information and display collected land rights data according to unique identifiers. MAST provides an integrated workflow for editing, processing, and approving land record data. Data of properties and other spatial units can be filtered according to their status.
Utilizing API and RESTful web services, MAST can be extended and integrated with other software. MAST works with specific services to allow consumption and integration of data to and from the data management platform. The MAST Data Management Platform API is Open Geospatial Consortium compliant and extends the well-known Geoserver API to facilitate easier interoperability between MAST and third-party systems.
MAST provides several layers of security by utilizing robust security measures. These measures operate at the database-level to protect personally identifiable information from unauthorized users. Security within the database is managed through business logic and is provided on a per user role basis. The data management platform allows administrators to define permissions for users for viewing, editing, and creating data, and assign credentials to users of mobile devices.
