DESCRIPTION:As vector data size increases\, the demand of cloud computing i
 s also getting more attention. This lecture aims to tackle the big vector 
 data problem and how to tackle it in the cloud environment. The introducti
 on of cloud-native vector formats such as Flatgeobuf\, GeoParquet and PMti
 le. We will have the hand-on visualization and process the big vector data
 set such as ICESat-2 and GEDI. The introduction and hand-on will combine w
 ith explanation of Vector \nTile and Lazy Loading theories behind.\nThe fi
 rst half is the lecture about the theory and algorithm behind the cloud-na
 tive format and spatial indexing. The duration is about 30 minutes. The se
 cond half is hands-on using DuckDB\, Polars\, and other python packages to
  work with cloud-native format. In addition\, we also will go through the 
 parallel processing for big vector data\, including parallelization using 
 semaphore for writing in a single big file and partitioning big data into 
 smaller chunks in parallel.\n\nOther links:\nhttps://docs.google.com/prese

DESCRIPTION:Digital Elevation Model provides knowledge of topography\, hydr
 ology\, geomorphology. Geomorphometry is a domain to extract the land surf
 ace parameters from DEMs. This tutorial introduces leveraging the state-of
 -art geo-processing softwares to create spatial information from DEMs.
