Hi Ed:
I know what you mean with some web sites being problematic to use, and the USDA has had an oddly independent mode of operation compared to other government agencies for many decades.
But since I've occasionally been told during irate phone calls with representatives of the USGS that some imagery I requested which repeatedly and inexplicably never had the online order fulfilled, was reportedly "
withheld" (not explaining whether this was due to homeland security or data management issues), I appreciated having the USDA site make the same imagery available via their servers when the USGS may have been having a "bad day".
Regarding your periodic failure to retrieve all tiles for a photoreal project via SBuilderX, you may be getting "profiled" by the imagery tile servers via your IP address or a cookie.
FYI: Luis Sa' has occasionally had to find new ways to work around
imagery tile server profiling of his DLLs used in SBuilder to deal with this problem, too.
If one has the more common "dynamic" ADSL ISP broadband type of account which allows periodic changes of IP address allocated to the "WAN-side" of ones modem or router (usually at intervals set by the ISP's DHCP server), one can also manually reset the assigned IP address
any time one wishes to do so. :iidea:
If one's DSL modem is in "
bridge" mode, one may wish to try forcing a "disconnect" of the broadband router via its GUI at
192.168.0.1 (most common modem or router address used in USA hardware).
Then one can re-connect to the TCP/IP PPOE under a newly assigned IP address via your ISP's DHCP server, invalidating imagery tile servers' "tracking and permissions" protocol for ones prior IP address.
If one doesn't use a router, and the DSL modem is in "
normal" mode", power off the DSL modem; within 60 seconds of powering the modem back up, ones ISP's DHCP server should have assigned a new "WAN-side" IP address to the modem.
At worst, one might then have to re-initialize the connection between the modem and ones computer by re-booting Windows; but one usually only needs to refresh ones browser or re-login to a website or imagery tile server in order to "
assume a new alias". :d
Upon returning the imagery website, one's computer may now look like a totally
different computer ...without a tracking profile, so the server may be willing to allow more content to be downloaded to one's system.
One may need to also clear one's browser cookies; in addition to the UI to do this in FireFox (or MSIE) browsers, one may wish to use Nir Sofer's "
MozillaCookiesView" utility from:
http://www.nirsoft.net/utils/mzcv.html
...or for MSIE browsers, "
IECookiesView" utility from:
http://www.nirsoft.net/utils/iecookies.html
Afterwards, one may need to manually restore a few cookies for convenience of auto-login at favorite, trusted websites such as SOH, AVSIM, etc., but this might help get rid of many tracking histories (in addition to imagery tile servers!) that slows down browsing... and limits one's imagery downloads.
I don't think imagery tile servers have begun logging MAC addresses yet; but if they do, rest assured that there is free and safe software one can then use to "randomize" one's MAC address in outbound TCP/IP data packets (this is done routinely for increased security by
knowledgeable IT administrators for large computer networks ...as well as "hackers").
Hope this might help you (and others here) to get more "immediate gratification" with your photoreal imagery scenery projects !
