Bagi yang meminati GDA ada sebuah tajuk yang boleh diusahakan sebagai projek kajian. Artikel berikut boleh diguna sebagai asas – ‘A rigorous and user friendly algorithm for global congruency test in geodetic deformation analysis. Kajian asal oleh Krzysztof Nowel dari Olsztyn, Poland. Paper kajian ini telah dibentang 2018 Baltic Geodetic Congress.

Berikut adalah extract paragraf kesimpulan artikel di atas:

Today, identification of stable PRPs in geodetic control networks is often done by GCT approach. Unfortunately, two conventional rigorous algorithms are not easy to use. As a consequence, its simplified forms are often used in practice or implementation mistakes can happen. In the light of the above, a new algorithm was proposed in this paper. This algorithm does not require a problematic decomposition step and, as such, can be easier to use in practice.

Austria adalah negara yang hebat dalam geodesi fizikal dengan tokoh seperti Helmut Moritz dan Hans Sunkel. Maka pastinya kajian mengenai geoid mereka sudah mantap. Namun negara Austria yang bergunung dilitupi Alps tentu ada cabarannya. Untuk mengetahui perkembangan geoid Austria bacalah artikel berikut;
