Dear all,
I need to project seafloor bathymetric data obtained in WGS84 format from GEBCO (https://www.gebco.net/) to use it as a explanatory variable for a habitat suitability model in the Southern Indian Ocean. Ideally, I would need an equal-area projection that would later help in evaluating the accuracy of the resulting models.
From reading ESRI and various other webpages it seems that Lambert Conformal Conic or Albers Conic Equal Area projection would be suitable options. In such case, I would be looking into centering the area of study at central meridian 70E and latitude of origin 30S. However, I can't figure out how to choose/calculate the two standard parallels (SP2) required to set either projection.
I have tried as a test to reproject in the socalled "Asia_South_Lambert_Conformal_Conic" (Central meridian:125; Latitude of origin: -15; SP1: 7; SP2: -32) and it works. Nevertheless, I would like the least possible distorsion and therefore to center it properly in the middle of the Southern Indian Ocean.
Any suggestions on how to achieve it and/or select appropriate SPs?
Many thanks in advance and apologies if the question is too basic!
Kind regards,
Berta
