Goa: region in India
What exactly constitutes the spatial extent of the city? For these aggregations, we used the Global Human Settlement Layer Urban Center Database (GHS-UCDB) to define the boundaries of the city. These cities -- or urban centers -- cover areas that are densely populated and built-up, and so may extend beyond the spatial borders of these cities that we may be familiar with. The GHS area is shaded in blue.

Most recent snapshot: Taking into account the entire (i.e. aggregate) street network in Goa as of 2014, the overall level of street-network sprawl is 5.17, which is highly disconnected.
Trends in street network construction: The SNDis of street construction for the respective time periods are 5.12, 4.69, 5.66 and 5.42. Disconnectivity in street construction in Goa follows a zig-zag trend. In 1976-1990, street construction was most disconnected, while construction was most connected in 1991-2000.
Quantity of street network construction: The street network in Goa spans a total of 4632 kilometers. It is dominated by roads constructed in 2001-2014. These roads have an SNDi of 5.42, which is highly disconnected.
Effect on the aggregate network: New construction in each period adds to the total stock of streets, but does not change streets that have already been built. Therefore, it has a limited effect on the street network as a whole. The SNDis of the aggregate street network in the respective time periods are 5.12, 4.89, 5.01 and 5.17. The SNDi of the aggregate street network in fell at first, but Goa has worsened in disconnectivity since 1990.
The level of street-network sprawl in new development in Goa followed a zig-zag trend with an overall increase. To get a sense of how street development has changed in Goa, we can consider three of its most populous cities: Panaji, Margao and Vasco da Gama. None of the most populous cities follow the same trend as the region. The level of street-network sprawl in new development in Panaji rose steadily. The level of street-network sprawl in new development in Margao was at its lowest in 1976-1990. The level of street-network sprawl in new development in Vasco da Gama followed a zig-zag trend with an overall increase.
