We recommend that rigorous line transect surveys must ensure: random transect placement with systematic and sufficient spatial replication to ensure adequate spatial coverage; coverage of sufficiently large areas in a short duration to ensure population closure; and investment of adequate effort to ensure reasonable number of detections.
While the inventory planner aims to ensure systematic spatial coverage when locating samples in a forest stand (Goulding and Lawrence 1992, Gordon 2005), there is little empirical information as to the importance of coverage, or guidance on the best way to achieve it.
Each of the three backpacks was carried along scripted walking routes that we designed to ensure thorough spatial coverage of all roads in the area.
Aside from our a priori classifications, we also selected sites representative of traffic to the north, south, and west of downtown Boston (which is located in eastern Massachusetts and is bordered by the ocean to the east), to ensure meaningful spatial coverage.
We then randomly selected from among these sites data not to be used for CV (ensuring reasonable spatial coverage within each region by manipulating the random seed), with the goal of making the data for 2000 similar to that in years prior to 1999 for the purpose of model fitting.
Therefore, ensuring spatial query integrity is critical.
Spatially balanced designs ensure there is spatial coverage of the entire survey area.
Finally, the use of satellite-based long-term average estimates of PM2.5 ensures virtually complete spatial coverage of PM2.5 among all cohort members.
Utilization of the coordinates of the LLRR and the radiotracked ALSEP sites located around the equatorial region (external) along with the formation of crossovers from the laser altimeter data records that are mainly located in polar region (internal) ensure a global lunar spatial coverage for comprehensive accuracy assessment.
To ensure long-term programs and wide spatial coverage, it is important to test the reliability of different cost-saving strategies that have been widely evaluated among researchers, such as taxonomic sufficiency, numerical sufficiency and surrogate groups.
Conclusion: The procedure developed enables complete coverage of targeted areas with larval control through comprehensive spatial coverage with community-derived sketch maps.
